    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.

Welcome all!

see you there :-)

nice, might be cool to allow for #4525 syntax to automatically link to the dweet
u/lionleaf

That's the plan mattdzugan :) Except d/4525, as # is reserved for hashtags

This was the thing at the top! I think this is awesome, but I'm, what, a 'framework kiddie?' I dig it though! Where do I start on here?
u/Serg

I see "Jan 1, 2018 7:39 PM" the date of post. Is it ok?)
u/sigveseb

That's the trick used to sticky the post :D the ranking is based on a combination of date posted and number of awesome. Future date == stickied post :D

A demonstration that abs(sin(x))**.9 is a good compact approximation of bouncing.

u/lionleaf

Nice! that's a useful trick! Why not just abs(sin(x)) though?
u/magna

**.9 compresses the curve and makes the restitution look more realistic.

Tasteful use of xor!

same effect can be done shorter with x.rect and x.fill('evenodd')

change that one 9 in the fillRect to a 8 and you get seamless waves! pretty!
u/Galaxtone

I don't see a nine.
u/Galaxtone

Also i had to change the 9,j) to a 10,j) at the end so that it looked correct.
