Did this cos as I wanted to understand binary numbers a bit better. The style is a nod to the Commodore 64, one of the first computers i remember (apart from the MicroBee) and named for its 64 KB (65,536 bytes, or 64 × 1,024 bytes) of RAM. Fun fact: 'bit' is a portmanteau of 'binary digit' and there's 8 bits to a byte, therefore 28 (256) possible permutations per byte. More at wikipedia.
