    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.

Moving 3D #Grid (improved)

u/Joachim

Nice!! You might find this helpful: with(x)for(i=z=c.width=400;i--;beginPath(stroke()))moveTo(i*9,99),lineTo(i*z-1e4,z),fillRect(0,99+i,z,(S(z/i+t*9)>.9)&&i/50)
u/lewdev

That's awesome! Thanks! I'm trying to figure out how to depict things in 3D; this and your website helps!
u/Joachim

u/lewdev no problem! Glad I could help out :D

Tiny Starfield 🌠🖱 Mouseover to change view angle!

u/cantelope

u/lewdev

Thanks u/cantelope but credit definitely goes to u/KilledByAPixel for making "Tiny Starfield" so tiny (93b)!
u/lewdev

I found a similar amazing use of onmousemove with d/24231 by u/Joachim
u/magna

You can avoid having to initialize X and Y by hijacking existing globals you don't use like T and R.
u/lewdev

Great tip u/magna! I was thinking about that a lot to cut out bytes recently.
