Downloaded this bad boy today.
You can see from the link it is a pretty revolutionary. It reminds me of the early version of Sega VirtuaFighter. Basically employs the same technology of motion capture on Uke and Shite and goes through 100 or so of the most common attackswith some search functionality as well.
Have been playing with this and although it is Aikikai and not Yoshinkan, it is still a very interesting product with temendous potential. I would like to see this applied to a lot of other products as well, especially ground work (like the Mark Hatmaker series on submission wrestling or boxing) and of course it would be good for things like dance lessons and the like.
Lots of ways I can think to use this as a training tool.
A lot of subtle parts of the macro movements, balance, and the like that you can pick up from this product.
