HN commenters link it as the easy way to see the giant home-built CPU without hammering the author's website.

A short tour of the Megaprocessor, a microprocessor built at enormous scale from tens of thousands of discrete transistors. The builder shows what the machine is made of and where it now lives, at the Centre for Computing History in Cambridge, where visitors can play Tetris on it.
