    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.

weird optical illusion after it finishes

u/iverjo

Oh yeah, it looks like there are white horizontal and vertical lines, but they are not actually there
u/joeytwiddle

Oooh yeah. I was only seeing grey dots at the intersections before, but on this bright monitor I can see the white lines too. *blinks*

Can you arrange the numbers vertically? Feel free to use the special moves!

u/Woodmouth

It's not a space limitation issue, it's a feature!
u/donbright

absolutley brilliant however e.x/e.y dont seem to work in firefox
u/joeytwiddle

Thanks don. I golfed this over a 24 hour period, but could not squeeze a better "valid move" rule in. Remixes welcome!
u/donbright

firefox should adopt e.x and e.y just so your dweet work
u/joeytwiddle

Hehe. Sadly the mouse coords are also problematic in fullscreen, and on mobile.
u/joeytwiddle

Valid moves are -4,-1,+1,+4. I have found a "valid move" test: **2|17)^17|| Will post the remix sometime.

homage to @literallylara 's 2025 with mouse.. (please try moving your mouse over screen)

u/donbright

thanks 2 @cantelope / @manga for T trick, @Jenky for mouse inspiration
u/joeytwiddle

I like the interactivity, and Firefox support. And one of the tricks is really going to save me some characters!
