Well, all that flash is impressive, but for me at least it is too too much. I can't navagate the site at all. I am on a PII 400 and it's really really choppy.
The flash is nice so the best advice I can give is to create a "Flash" and a "Non-Flash" version. Please keep in mind people who aren't on Athlon MP 1.2 Ghz x2 4GB DDR Windows XP boxen... some of us use P1 233 with 64 MB RAM and Linux.
