m8trix 8b was created by Hellmood and is 8 bytes in size. Actually, it has been optimized to 7 bytes (!), but let's start with the original. m8trix 8b started out as these 8 bytes:
org 100h
S:
les bx,[si] ; sets ES to the screen, assume si = 0x100
; 0x101 is SBB AL,9F and changes the char
; without CR flag, there would be
; no animation ;)
lahf ; gets 0x02 (green) in the first run
; afterwards, it is not called again
; because of alignment ;)
stosw ; print the green char ...
; (is also 0xAB9F and works as segment)
inc di ; and skip one row
inc di ;
jmp short S+1 ; repeat on 0x101
