    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.

I'm working on a version with green mountains and water but I need to shave a few bytes of this one first. Suggestions welcome

wow very nice
u/alien

is this what they call raymarching?
u/aleamb

yeeeeeeeeeeeeeeeeeeahh awesomeee!

Both 240, 120 and 60 are multiples of 60 so I think you can lose bytes by making 60 a constant... somehow. Right?
u/keithclark

@alien - no raymarching here. This is a cos() generated waveform, drawn from back to front.

[Game] This game involves clicking flying money. The objective is to keep the supply of money coming for as long as possible by clicking the money before it escapes. However some of the supply is counterfeit, and clicking on counterfeit currencies lead to consequences.

u/lionleaf

Awesome dweet! Looks like jquery has snuck itself in, so unfortunately this dweet will break in the future, as I plan to remove jquery access for the dweets.
