    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.

Accurate Relative Scale Solar System

u/tomxor

1000 kilometers per pixel, and 1000 seconds per second. Inspired by d/26463 An orthographic projection (i.e no perspective), imagine looking at our solar system through a telescope from a distant alien world. All scales are accurate relative to each other, radi, mean orbital distances, and sidereal orbital period. This is only possible by lining up the planets and looking through the orbital plane, but due to the massive orbital distances they all shoot off screen quickly.

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!
