As advertised on yesterday evening's episode of Life (which you would be literally mad not to watch – catch it on iPlayer) you can get a free poster courtesy of the BBC and Open University. The poster appears to show the branching tree of evolution and species, but I haven't received one yet to see it in its full glory. In fact I may have to wait as they seem to be struggling to satisfy demand and the website itself is a bit flakey right now too.
