    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.

Saved 9 more... although it decodes at 1 bit per second !!

u/tomxor

Decoder now = 90 chars, leaving 50*20/7 = 142 chars of content yay! +2 chars
u/tomxor

To break even with 184 chars, 184*7/20 = 67 20bit chars, leaving 73 for decoder, not sure this is possible :/
u/tomxor

... I guess 1bit/s is just not good enough for the internet of the 21st century XD

#tree #waitforit #uncompressed

u/pavel

This is a breadth-first traversal of a binary tree, one frame at a time. The tree is maintained in a 1D array (2n+i notation) that I simply iterate left-to-right. The loop does double-duty for drawing the current node and inserting the children. The shape has four corners so the loop runs four times and inserts four children: 2n+0, 2n+1, 2n+2, 2n+3. My mind was blown when I realized no extra code was needed to prevent the adding of the extra children because the first two children of the next iteration will overwrite them!
