    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.

That's a really clever illusion, love it
u/magna

Heh, thanks! Brought it down to 123 chars in hopes of adding occasional mistakes like skipped characters / typos etc., but couldn't immediately find a way. In case anyone wants to give it a shot: https://www.dwitter.net/d/2522
u/donbright

u/Polyducks

Could you make a random function to skip odd spaces?
u/magna

It has to be a deterministic PRNG so that the places that are skipped are persistent. Otherwise, it would just look like a random flipping of characters. I thought about it, but couldn't immediately find a short solution.
u/Polyducks

That's a great point. Dwitter is such a mind twister!

i literally laughed out loud playing this
u/joeytwiddle

Brilliant :D
u/Woodmouth

Hmm, there is actually quite a bit of space left. Can anyone make it follow the mose?
u/Woodmouth

Or wait... that would require a lot actually, nvm, i doubt it will be feasible.
u/joeytwiddle

I could get it to chase the mouse but could not keep the edge detection: https://www.dwitter.net/d/2495
u/Woodmouth

The slow turning is exactly what i was thinking of. I've already asked once, but why not again? Is anyone able to compress the last 12 characters in joeytwiddle's 2495 with the slow turn addition?
