    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.

Projection Faster and Uncompressed

u/@noel

I love this one and I follow the logic, until the z & w performing. I know it's a bitwise AND operation on z and w, but I don't actually grasp it.
u/@noel

I mean on this one: x.fillRect(i, j, 1, (z & w) / w)
u/joeytwiddle

Here (z & w) / w is the height of the rectangle. If that height is less than 1, then the canvas anti-aliasing renders a grey pixel, instead of a black one.
u/@noel

Thanks u/joeytwiddle Now I think I get it. (z & w) ensures that the value of z remains within the range of the canvas width 'w', and the dividing by w normalizes the height value. Great trick!

Verified - Dwitter Not For Sale

u/tomxor

hah, that would be horrible - I think we are protected by a nice thick layer of obscurity though ;)
u/KilledByAPixel

someone just offered us 44B for dwitter! yes, you read that right 44 bytes. :)
u/384.cz

funny, KilledByAPixel
u/lonestar108

You should charge $8 a month and let those people post 280 character dweets, I guarantee you there are a non-zero number of people who would pay for that.
u/joeytwiddle

we could do a lot with 44 bytes
