One complaint, though... the initial flash page takes way to long to load, I have a 1,5 Mbps ADSL line and even if it didn't take more than like 10-12 sec, it was on the heavy side (most people still has far slower internet access than that...) Maybe a bit weight trimming and optimalization is possible...
overall I really like it, the only think I found slightly distracting was the fact that the white outline on the blender/nav flashes and changes every time you click something. Personally I'd have the blender transition in only on the initial load and then just lave it as is for the rest of the time.
Have the content do it's neat little transitional thing but the blender is really un-needed because it's not really changing.
I think it looks really good. One thing that I would recommend is to change either the BG color or the color of your content. There doesn't seem to be quite enough sepeartion in my opionion between greens. Other than that I like it. Good job.
