In general, I really like the look (CSS3 + HTML5 = Awesome!), but maybe you should have linked to the "about" page, which is a wee bit more explanatory than the demo of your links.  It takes a minute to figure out that "slices"  and "bites" are a play on the "pie" aspect of the name . . . maybe change the logo to birdPIE to make it a little more intuitive, or perhaps include a pie-like spatula or a fork icon beside the links for people to "get" the lingo.
