    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.

Circuit Diagram

u/tomxor

Nice! most convincing xor sampling #circuit pattern i've seen, lots of ball grid arrays
u/ntsutae

(i-t)^(i+t) is great.
u/rodrigo.siqueira

Change ^ to | and you will see falling Sierpinsky triangles! I mean: (i-t)|(i+t)
u/ntsutae

Yes, I've already tried "|","&". The triangles appeared without the use of recursive call. Dwitter told me bit operation skills. Thank you.

Text editor with auto-save. Type and reload (or come back later). Your edits are stored in this Dweet.

u/rodrigo.siqueira

Shortcuts: control-b (bold), control-i (italic), control-u (underline). You can even paste html in this Dweet.

Sorting the four fours numbers! #waitforit #math #puzzle. This is an automatic program that will throw the list of natural numbers written as javascript expressions that eval that number! To view the code, replace eval with throw

u/katkip

example print: 1 = 44/44 2 = 4/4+4/+4 3 = 4+~44%4 4 = ~44%~4^4 5 = 44%4-~4 6 = 44/4+~4 7 = 44/4-4 8 = 4+4//-/^*4^*4 9 = 4/4+4+4
u/KilledByAPixel

nice!
u/katkip

looks like it gets stuck at 17
u/katkip

17 = 4^4*4-~4 18 = 4-~4+4-~4 19 = ~-4^~-4*4+4 20 = 4&4^4*4 21 = 4/4-~4*4

nvm. stuck at 22
