I love it, but the server seems overloaded. Because it reacts so slowly it's a bit hard to tell what's going on. What does the "Progress" stat represent, exactly?
Research has shown that making a selection between a limited set of options a large number of times is very exhausting for the brain. So I don't think this is really a good solution to any problem. But it is interesting, nonetheless.<p>A better idea could be to present these options while the subject's brain is being scanned using some neuro-imaging technique, and based on these signals let the system evolve.
If you enjoy this logo-evolution idea, you'd probably also enjoy Picbreeder (<a href="http://picbreeder.org/" rel="nofollow">http://picbreeder.org/</a>) which allows you to breed pictures (generally, not only restricted to a particular logo) represented by neural networks, through an evolutionary algorithm.
