    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)

The way he disappears makes me think he was being slowly shot away. Why didn't Space Invaders sometimes have a formation that looked like a huge space invader?

Size limitations probably. The creator of Space Invaders originally made it 7KB but he stripped it down to 4KB to fit in the ATARI of the time
