Whilst browsing the net I came across, probably one of the most interesting tools for Aikido training Ive ever seen.
Its definitly worth a look and I'll definitly be buying it...once I can afford it, lol
Its called 'Aikido3D' and Ive included the link below.
Take care of each other
PS, before anyones mentions, I do realise this is for a certain 'style' of Aikido.
