I found a nice little training aid. Check out www.Aikido3d.com
. It uses motion capture technology so that you can watch a technique as slow or fast as you would like. You also get to modify the angles you see it from. Very useful for kyu ranks because you can view all the 5th thru 1st kyu requirements. It features the aikido of Donovan Waite Shihan. I feel it is worth a look, especially for those who may be taking a kyu test.
