How the Foundation Print Is Drawn, and What Every Shape Means

Foundation is a modular grid of circles, arcs and bars in primary colour, set as a poster. It is the composition we generate first, and it is deliberately the one that looks least like an artwork and most like an exercise. That is the point. At the Bauhaus in Weimar, every student began with the preliminary course, and every preliminary course began with the same question the poster asks now: what does a shape do on its own, before anyone decorates it. Foundation is drawn to be read, not admired.

The Grid Beneath Everything

The first thing to see in Foundation is the grid, and the second thing to notice is that most of the grid is invisible. The composition sits on a modular field of equal squares. Every circle is inscribed in one of those squares. Every bar is one square wide and some whole number of squares long. Every arc is drawn from a corner of a square, with a radius equal to the side. Nothing floats. Nothing is measured in millimetres by eye. The rule is stricter than the picture looks.

The grid is invisible because it does the work a foundation is supposed to do. You build on it and then you walk on the finished floor. In Weimar the preliminary course taught the same discipline before it taught anything else: a square is a decision about where the next shape can go. The students who resisted it, and there were many, produced compositions that later teachers called restless. The students who submitted to it produced work that looked calm even when it was loud.

In Foundation we keep the module coarse on purpose. A denser grid would let the composition wander toward pattern, which is the opposite lesson. A coarser grid forces every shape to matter. Count the units across the poster and you will find a small number: seven, eight, sometimes nine. That is the whole vocabulary. The seed can move a circle from one cell to another, but it cannot invent a cell between two cells. This is what generative geometry inherits from the preliminary course. The constraint is the teacher.

There is a second grid we should name, because the eye reads it whether or not it thinks about it. It is the grid of margins. Foundation leaves the outer squares mostly empty. The interior does the talking. This is not decoration. Modernist posters from the Dessau years treated the margin as structural silence, the way music treats a rest. Read the poster with the margins in mind and you will notice that the loudest square is never against the edge. It is one step in.

Why Red, Yellow and Blue, and Nothing Else

Foundation uses three colours and three only: a warm red, a full yellow, a deep blue. There is white for the paper, black for weight, and no other hue anywhere. This is not aesthetic austerity. It is doctrine.

At the Bauhaus, Kandinsky asked students to fill in a small questionnaire on colour and form. He wanted to see whether people would independently assign yellow to the triangle, red to the square and blue to the circle. He believed each pairing was necessary rather than arbitrary. Whether or not the questionnaire proved anything, the primaries themselves were treated as the base grammar of colour. Any secondary — orange, green, violet — was understood as a compound, a mixture, a sentence made out of the base words. To learn colour, you first learned the words.

Foundation refuses the compounds. A first exercise cannot afford ambiguity. If a circle is blue and a bar is red and an arc is yellow, the eye can compare their weight, their forward-and-back, their apparent size, without also negotiating a temperature the artist added on top. Put a violet in the composition and half the reading collapses into taste. Keep it to red, yellow and blue and the reading stays about shape.

The three primaries also disagree with each other in a very specific way. Yellow advances and feels light; blue recedes and feels heavy; red sits somewhere near the picture plane and refuses to move. Place them together at equal area and the composition will look lopsided until you learn to compensate — usually by giving blue the largest field and yellow the smallest. Albers spent years teaching this by making students place identical squares of colour against different grounds and watch them change. Foundation does not stage that trick, but it obeys the lesson. The yellow shapes in the poster are smaller than they look. The blue shapes are calmer than they weigh. That is deliberate.

The absence of a fourth colour is the loudest choice on the sheet. It tells the reader: this is a study, not a decor object.

The Circle, the Arc and the Bar Doing Different Work

Three shapes carry the whole composition, and each one is doing a different job.

The circle is the anchor. A circle has no orientation. Rotate it and it does not change. That makes it the only shape in Foundation that reads as a fixed point. When two circles appear on the sheet they act as poles, and the eye travels between them along whatever path the other shapes lay down. When a single large circle appears, it becomes the centre of gravity for the whole field, and every other decision is measured against it. Kandinsky called the circle the most peaceful of the primary forms. In a first exercise, peace means: the thing you can trust while you experiment with everything else.

The bar is the line that has been given a body. It has direction, length and weight all at once. A horizontal bar in Foundation lies down and stabilises the composition. A vertical bar stands up and cuts it. A diagonal bar — and this is where the poster becomes an argument rather than a diagram — does work neither of the other two can do. It carries the eye across the sheet at a speed a horizontal cannot match. The preliminary course teachers made students spend weeks on the diagonal, because most beginners avoided it. Foundation does not avoid it. When the seed places a diagonal bar, the whole composition tilts into motion, and the circles have to hold their ground harder to keep the picture from sliding.

The arc is the compromise, and it is the shape most people miss on a first look. An arc is a fragment of a circle that has been given direction. It curves, so it belongs to the circle family; it points, so it belongs to the bar family. In the Bauhaus grammar this is the shape that lets a composition breathe. A field of circles and bars alone can feel like a machine schematic. Add an arc and the picture recovers its willingness to be looked at. In Foundation the arcs are almost always drawn from a corner of a grid square with a radius of one full side, which is why they read as parts of a larger, implied circle sitting just off-picture. That implied circle is what makes the composition feel bigger than the paper.

What the Seed Decides and What the Tradition Decides

Foundation is generated by code from a deterministic seed. The same seed always produces the same poster. Change one digit and you get a different composition, but you do not get a different tradition. This is worth being precise about, because generative art is often described as if the machine is the author. In Foundation the machine is the student, and the tradition is the teacher.

The seed decides positions inside the grid. Which cell holds the large circle. Which cells hold the smaller ones. Where the diagonal begins and how far it runs. Which corner the arc opens from. How much of the sheet stays empty. These are the choices a preliminary-course student would have made with paper and cut card at a Weimar workbench in 1923, and they are the choices the code makes now with a pseudo-random number and a rulebook.

The tradition decides everything else, and it is the longer list. The tradition decides that the palette is the three primaries plus black and white and nothing else. The tradition decides that shapes sit on the module rather than between modules. The tradition decides that a bar's width is one unit, that an arc's radius equals a cell side, that a circle inscribes its cell rather than overflowing it. The tradition decides that the margins are broad and structural. The tradition decides that there is no gradient, no shadow, no rendering trick that would let a flat shape pretend to be an object. Every one of these constraints comes from the same place: the school taught that decoration is what you resort to when your composition cannot stand up on its own.

This division is why two Foundation posters generated from different seeds feel like two exercises by two students in the same class, rather than two artworks by two different artists. That is the correct outcome. A preliminary course produces a room full of studies that all share a grammar and each say a different sentence. If our seeds produced work that felt stylistically independent from each other, we would have failed the tradition, not honoured it.

Reading Foundation on a Wall

A poster on a wall is not the same object as a poster on a screen, and Foundation was designed with the wall in mind. Three things change when the print is hung.

The first is scale. A circle that reads as a token on a phone screen becomes a physical presence at fifty centimetres across. The room begins to negotiate with it. Furniture below the print stops competing with it once it is clearly larger than any single object on the floor. This is why we recommend printing Foundation big enough to be the loudest shape in its wall, and hanging it with generous space around it. A modernist composition treated as a small decorative accent contradicts its own argument. It was drawn to structure a room, not to sit inside a gallery wall of small framed things.

The second change is light. The primary colours in Foundation are chosen to hold their identity under ordinary daylight and ordinary tungsten. They do not need gallery lighting. But warm evening light will pull the red forward and dull the blue; cool morning light will do the opposite. This is not a flaw. It is what happens to primaries in real rooms, and it is what Albers taught students to expect. If the poster looks slightly different at breakfast and at dinner, the composition is behaving correctly.

The third change is proximity. Foundation rewards being read from close range and from across the room. Up close, the grid discipline becomes visible: you can see that the bar is one cell wide, that the arc really does begin at a corner, that nothing is nudged for prettiness. From across the room, the composition becomes a diagram of weights and directions, and the reasons for the layout become legible in a way they never quite are on a screen. Most artworks are made for one viewing distance. A preliminary-course study is made for two. That, more than anything else, is why Foundation belongs on a wall rather than in a folder, and why it sits in our shop as the first composition and not the fanciest one.

Foundation is the exercise the school began with because the school believed that once you can read a circle, a bar and an arc, you can read anything else that will ever be put in front of you. The poster is a small argument for that belief, drawn in the smallest vocabulary that will hold it up.
