Greg,
if done right, this could probably be a good product. But I'll let ya in on a little secret, but don't let it discourage you. We promoted a similar piece of content, but it didn't sell well. It seems that many companies aren't interested in such items, but I guess this is also very dependent on the quality of the product.
Good luck with it! I would suggest making it a video product, not flash/shockwave. As a 3d artist, I know how tough it is, but it's hella fun when you see the result!
