Interpretome (http://esquilax.stanford.edu) is pretty cool. More fun that serious, but well worth checking out. Nice (though surprising!) to know I'm not really a Neanderthal! The population genetics tools are fast and make very pretty pictures. Disease stuff is not as good as 23&me but I didn't explore it fully.
Another program which I currently have running is Promethease (http://www.snpedia.com/index.php/Promethease). It's currently querying SNPedia with my 23&me data.
