Definitly one of the best 3D sites done in Flash is The Eco Zoo. It is surely great designed and very unique, with remarkable performance. Pop up books are so cool 🙂
Uniqlo hits it again with Uniqlo Try. Camera movements are really Uniqlo style, music and feeling at the site is great as always…
Third in series is Play > Smart, advertisement site for Benz-Mercedes mini car. Design of the website could be better as well as the texturing, but site definitly have a good catch with game mode and keeping score live.
Things are going in good direction, and I think web people will follow.
