This is awesome man. The wife and I just spent 30 minutes scrolling around and added quite a few items to my Favorites. You need to find a way to get an affiliate fee as soon as possible!
The Pinterest-influenced UI is such a great way to explore. I'd much rather browse around on your site than the actual Etsy site anyday. The new items flying in from the left does catch me off guard sometimes and I think the search input and browse dropdown need to be a bit larger but other that, very well done.
