This is a great example of the point the guy is making: https://www.youtube.com/watch?v=36BPql6Nl_U https://www.youtube.com/watch?v=36BPql6Nl_U That's 128 bytes. You could encode that as a 43 pixel RGB888 image. That's less than 7x7 pixel icon! Now as Jare mentioned in another comment, this video http://www.youtube.com/watch?v=jB0vBmiTr6o http://www.youtube.com/watch?v=jB0vBmiTr6o contains less bytes than a basic 32-bit 32x32 pixel icon. Some of the whole essence of this demoscene stuff is to work within these constraints(256 bytes, 1024 bytes, 4096 bytes, 64 kbytes, ...) to produce this kind of art. Custom virtual machines, on-fly decompression algorithms and methods, carefully crafted data and ingenious ways of data re-use are the key. It's like black magic.
