Very very cool. Couple of quick thoughts though:

1. I'd like to be able to see a brief bio beside an image when I click on it and the lightbox opens, preferably with links to other work

2. The ability to filter by style and genre would be useful

3. It looks like it doesn't save selections if I hit the back button. That's a no-no for usability

I'll have another think in the morning and post any further thoughts then.
