    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

:o
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!

Woodmouth's ant chasing your mouse

Show more comments…
u/joeytwiddle

Since I couldn't fit the edge detection, I stop the ant when it reaches the target. So I stored the target in k,j
u/donbright

this mouse technique is excellent
u/joeytwiddle

To make him a slow turner: D=(Math.atan2(j-b,k-a)-d+3.14)%6.24-3.14;d+=.05*D
u/joeytwiddle

err I mean 6.28
u/Woodmouth

That's impressive. The slow turn was exactly what i was looking for, but that is sadly just a bit too big.
u/MrM@_S

K=3.14;d+=((Math.atan2(j-b,k-a)-d+K)%6.28-K)/20

u/magna

I was expecting this to happen one day...
u/magna

Wait. How the hell are you rendering the "ground"? I don't get it. Explanation please.
u/nystrand

It's the "(O" chars at the beginning of the code decreasingly scaled down from the large initial scale. I had to find a variable name that "looked good", - went with O which made coding confusing as it looks like a zero :)
u/magna

This is nuts!

just replace 𝘼𝙋𝙀𝙍𝙏𝙐𝙍𝙀 with Aperture. Which also is a bit heavy on the byte count.
