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 uncompressed code: z=500;x.fillRect(0,0,z,z);x.fillRect(z+100,0,z*4,z/3);x.fillRect(z+100,z/1.5,z*4,z/3);x.fillRect(0,z+100,z*4,z/3);x.font="500px a";x.fillText("◤",z-100,z+z);
Hi :) your code can be shortened so that it fits into 140c without compression : z=500;x[s="fillRect"](0,0,z,z);x[s](600,0,z*4,z/3);x[s](600,z/1.5,z*4,z/3);x[s](0,600,z*4,z/3);x.font="500px'";x.fillText("◤",400,z+z)
