My sensei and our Dojo is very open minded and new variations are always welcome. I must say that Aikido3d is far superior to any tape that I have seen or own just because I can change the angles of view and zoom in on the movements I find interesting. This allows for the study of the technique in much more detail. Videos are 2D period Aikido3d is in a virtual 3D world and it allows the viewer to view the movement in 3D. I strongly recomend it.
