    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

is this what they call raymarching?

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.

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.

You could use clipping to have the pointing hand disappear into the OK hand if you placed the clip rectangle just right. I don't know how you would save up the characters though, maybe by using a for loop to only have one fillText call (but that would also eat characters with all the ?: statements you'd have instead).
u/magna

Yeah, clipping would make it awesome! Let's see if this can be golfed down significantly to open up space for some clipping.
u/Agnes

I posted a clipping remix. You can do scaling, translation and rotation in a single call to setTransform.

Damn! Worked on Chrome on my Android, but not Chrome on my Mac (weird). The building isn't visible. #emoji
u/joeytwiddle

256px is the highest you can go on Mac Chrome, 324px on Mac Firefox. To work around, scale down the canvas.
