u(t) is called 60 times per second.
t: Elapsed time in seconds.
S: Shorthand for Math.sin.
C: Shorthand for Math.cos.
T: Shorthand for Math.tan.
R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
c: A 1920x1080 canvas.
x: A 2D context for that canvas.
This code was 100% created by OpenAi's GPT-3. My input prompt was the #default (New dweet) code followed by a comment line: "// Improve the code above". I only removed the comments generated by the AI and the resulting code fits in 139 chars. The generated comment was "// Draw a circle that moves around the screen" and "// clear the canvas" in the first line.
i did have the idea of feeding GPT-3 every single dweet to see what it came up with, but i never got round to it.
