    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.

Infinite hopscotch

u/Odog8

Thats nuts
u/Joachim

This 3D-like technique is useful for making single-direction ground textures. This is roughly how it works: A rectangle with a height of ~1px is drawn for every row of pixels on the screen. The width of every rectangle depends on how far down it is (their index). The x position of every rectangle is defined by this bit of code: T(z^z/i+t*9). This is then multiplied by their index to achieve a 3D look, as everything gets bigger & faster near the bottom of the screen. Without the animation or colours, the entire thing can get as small as 64 char: for(i=z=c.width=300;i--;)x.fillRect(140+T(z^z/i+t*9)*i,90+i,i,1). Feel free to get it even smaller!
