    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.

Float64 Encoder #application

u/tomxor

Enter a number and click away to get the underlying binary64 IEEE754 encoding with a space separating the exponent and significand.
u/tomxor

This uses the new proposed BigInt64Array typed array view to access the binary encoding, so it currently only works in latest chrome.

u/tomxor

Nice analogy :) like a TV into the computable universe, infinite channel! (sorta)
u/21medals

Why the space in between each character of E?
u/tomxor

Because -- and ++ are assignment operators, and I cannot allow those on loops variables X and Y. It's basically cheaper in chars to pad with spaces than test for this with a regex.

Inspired by u/anotherkitten u/21medals This is more likely to draw something by focusing on the [x,y] = f(t) solution space and further reducing that to interesting ones by manipulating allowed input tokens.
u/tomxor

Familiar yet different every time :)
u/tomxor

Trust me, it will draw :P every time the comments bounce it's found a solution and assigned it, but not all combinations draw anything visible.

Trinitron #crt #scanline #fractal

u/tomxor

Finally resorted to UTF8. This is a reasonably accurate slow motion aperture grille scanline animation... Although if run very slow you will see it's not simulating 3 electron beams. t=fps (scanline) w=width (subpixels) the later must be a multiple of 3 and 5. Use X, Y and floored F to plugin your own fractal!
u/tomxor

Uncompressed: w=90,i=l=w*w/5,t=1+t*t/12; for(x.fillRect(0,0,c.width=w*2,w*2);i--;x.fillRect(X*6,Y*6,1+K,5)) X=i%w/3,Y=i/w|0,F=t-i/l,K=1-F%1,K*=(Y^X-~F)/27%1+K**8, x.fillStyle=hsl(${i*120},99%,${K*99}%)

Awesome!
u/magna

I had a RGB CRT setup, but I hadn't been able to fit any interesting patterns: d/7512
u/tomxor

I had a look at yours magna, they are true crt, much more realistic i think. The scan lines on this are just a sideeffect I exploited and it was easy to add colour distortion in the R().
u/magna

Here we go: d/10843
u/C010011012

is it a cellular automata?
u/tomxor

Yes and no, it's a fractal n=T(0|(i/w+f^f-i/w)/(t**.7+6)) which is just a more elaborate variation of serpinsky triangles to produce more interesting patterns. Some fractals are automata, but not all automata are fractals, see here: https://en.wikipedia.org/wiki/Rule_90
u/tomxor

The implication is serpinsky triangles are computationally reducable, meaning it does not have to be computed in the same way as a cellular automata i.e state can be computed at step t directly without traversing intermidiate steps.

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.
