First off, very nice site. When I first saw "evaluate" and "flash" in the same sentence my first thought was to cringe that another person had epically failed at making a Flash website. I was wrong! (and happy). This is possibly the best implementation of a Flash website I have ever seen. But, like everything, it has a few issues.
First of all, I am viewing the site on a 1024x768 screen. Even though the flash area its self fits (luckily) the area around does not, giving me scroll bars. When I first saw the site it took me a few seconds to figure it out, seeing as I could scroll in the flash AND on the page I thought I was always going to have content clipped, luckily the flash fit. So if you were to make the flash scalable or just make it smaller that would be great.
The only other thing I noticed was on your Flash section the text is very small and black, making it almost impossible to read. This should be very easy to fix.
After that, if you could implement a way to 'lock' to mouse to each area (video, flash, about) so once you have the mouse over the object have the background not scroll anymore until you move your mouse again.
Lastly, you should give your flash section a desk. After clicking on it you are brought to a computer floating in mid air. This isn't a big issue, but I think it would just look even better.
Even though I listed a lot of issues, I'm still very impressed with the site. Good job!
