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.
original code slightly modified and compressed:c.width*=1 p=(m,n)=>(8+C(8*m))*(1-((n+6)/12)**3)**0.5 for(j=-6;j<6;j+=0.1)for(i=0;i<6.28;i+=0.05)x.fillRect(960+540*((j+6)*C(j-t*9)/14+S(i)*p(i,j))/(14-C(i)*p(i,j)),540-540*j/(14-C(i)*p(i,j)),3,3)
i should have clarified but the code in the title was the original code i made. i had to change p to a variable instead of a function but i wanted to preserve the old code. also i do know about beta dwitter
