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.

• Prime fun 2 / 3 - Normally X binary XOR with Y produces a single white line, but if we only draw black when X XOR Y is a prime number, then we get a pattern. #math #primes

• 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.
