Take a look at this website:
www.aikido3d.com
It has a product on there much like an instructional DVD, but in 3D graphics. The website states that you can view the technique from any angle and zoom in etc.
My question is, is it any good? Things like finger placement for kotegaeshi etc could be an issue in my mind. I would like to know from someone who:
A. Owns the product
B. Does not work for the company/producres
