    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.

@donbright, are you challenging me to make something different? I accept!

we are not worthy
u/cantelope

oh u
u/cantelope

@donbright, i did not mean for my statement regarding a challenge to sound arrogant, but I see it came across that way. I just meant, you are correct that i do a lot of wireframe dweets, and I'm enthusiastic about trying something new! I hope we're good. Love your work!
u/Xen

its hard to figure the emotion behind a comment sometimes, which is why i ALWAYS spam mine with smileys ;-)
u/donbright

no its fine, my words dont come across in ASCII very well
u/donbright

i am in awe of everyone here, my mind constantly boggles at the skill and techniques of all of the people here. i have a special affinity for wireframe for some reason.
u/donbright

i mean i like looking at wire frame, but im not that good at making it, so its cool to see it.
u/cantelope

It just loads forever :P
u/joeytwiddle

Oh I didn't realise it was suppose to finish loading!
u/magna

Yes, ideally, the loader should show progress when t is between 0 - 1. But I think infinitely loading progress indicators like these are totally fine as well!
