I am studios
I have never been a fan of flash sites. A bit of flash is fine to jazz up a site, but I find full flash sites annoying, slow to load and just plain pointless. Combine this with the fact that you are essentially counting yourself out of any decent search engine traffic and you have got an internet disaster on your hands.
And then I found I Am Studios. This is one of the best flash sites that I have seen. It got my attention, made me laugh and promted me to send it to a few friends. I will even go as far as saying that it makes all the negative side effects of using flash worth it.
