This is more of an artistic program. By left-clicking you set a fix point and define a random color. Where you then move your mouse, the program will draw 𝟣𝟢𝟢 circles in between the fix point and the cursor position. By right-clicking you save those 𝟣𝟢𝟢 circles on the canvas. Holding the right mouse button is possible.

Controls

• Left clicking sets or removes a fix point,
• Right clicking saves current circles on canvas,
• ‘s’ saves current canvas,
• ‘c’ clears current canvas.

Playing around with angles and my `getCirclePos()` function, I came up with these little entities. They have a center, a distance to that center and an angle which constantly increases. Those parameters also randomly change.

Being fascinated with how prime spirals look, I tried another layout for primes. Starting at the upper left and writing out numbers like a normal text, starting at 𝟢 and coloring every prime number red, every other number white, this is the result.

It is interesting, that — like in prime spirals — the red squares form visible patterns. Randomly assigned squares would not as often form such patterns.
