It serves its purpose but there's not a lot to go on in terms of content. There's nothing on the front page except a block of text, which I'm sure is interesting if you already know what the site's about. You could possibly make the 1 minute demonstration a little smaller, place it on the front page, slow it down a bit and throw in some explanation.
I can't really say what would be the best unless I know whether you're aiming this at people who know what you do? Or people in general? Also you should look into replacing the text images with regular Html/CSS text, because the load times are rather harsh and, well, the page loads like an image, in a slow downwards television way.
There should also be a contact section for people who are interested as I barely noticed the E-Mail address posted at the bottom of the main page. Hover effects on the links would be a good investment too. This all sounds like I'm bashing you, but if you get these things fixed it should turn out great and more user friendly

I hope I didn't twist the knife too much!
