    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.

Huge improvement over my last Mandelbrot! I learned some tricks from y'all :D

Just noticed that this looks different on different computers because of the fillText(). It also looks trippy if you resize the page!

My first dweet! Tips for working in javascript would be appreciated since I've never used it before

u/jellyedwards

Hey Piggo, to reduce a few chars you don't need var, you can do -- instead of -=1 and you can put some statements in the last term of the from expression, have a look at this that does the same in 116 bytes: Z=Math.abs(T(t/3));for(X=90;X--;)for(Y=90;Y--;x.fillRect(X*10*Z-50,Z*Y*10-50,9,9))x.fillStyle=hsl(${t*150},95%,45%
u/jellyedwards

Hmm the back quotes for removed from the hsl but you get the idea!
u/Piggo

Awesome, thanks for the tips!

Mandelbrot set! It's crappy, crooked, and compressed but I was really fighting for every last character
