Yeah just three weeks ago. The proofs are all complete and the guy in charge of writing it up should almost be finished. It'll probably take some time to get published though. I met Conway at a maths summer camp in Germany, and he told us students about the Prague clock problem. A friend, a grad student volunteering there, and I worked on the problem for a few days and pretty much solved it, and Conway said we should write a paper together. I was incredibly lucky, of course. Recreational mathematics isn't how one expects to get an Erdos number. It was a wonderful experience, and John Conway is an amazing man. I've never seen anyone that could delight so much in almost trivial mathematics. Kinda explains how he became great.
