Looks like the idea is to implement a cellular automaton with a different ruleset on top of Game of Life (using so called metapixels), and then use that to implement a CPU. This is similar to the Wireworld computer. I liked this quote on its website: "The design was done by David Moore and Mark Owen, with the help of many others, between 1990 and 1992. It’s a testament to our modesty that it was not until September 2004 that we wrote up our work." I shall start using that euphemism!
