I think there is not enough info about this software to simply say it's useful or not. I find it a bit disappointing it's WTF (as personally I would have liked to see ITF and Tuls haha), but from what I have seen this might come in handy (not only for amateurs).
I hope it contains all types of 'Matsoki's'.
I'll keep an eye out for it, thanks for letting us know.\
And as for the price, I went to the site of Aikido3D (as advertised on the TKD3D site). It says the regulair price is 75,95 (US Dollar), so maybe this goes for TKD3D aswell?
Wow, I see it is a download version, that's pretty cool (sometimes I can't order these kind of things because they dont ship outside US and Canada).

*ressurrects the topic*
TKD3D is now available. Apparently there are 2 products, one for WTF style taekwondo in general, and one focused on competition.

I'm interested, but I'll probably not buy it anytime soon (it IS expensive). Anyone here wanna try it?

Anyway, I had submitted my email to receive free shipping, but I haven't received any message from them. Apparently it was just marketing..

Edit: Apparently, free shipping is available for everyone

I would very much like to get my hands on something like that. I'm hoping someone will upload it so I can snatch it. I myself have an interest in teaching, traning, and coaching others so I like to use all sorts of different tools and methods in my lessons. Not everyone learns the same way and sometimes there are those who require much more finer detail than is humanly possible to demonstrate, perhaps using this 3d software offers the pin point accuracy that some particular persons need to comprehend a technique.

Okay, this thread is a little old but I'm a new member so can I get away with responding to this?
I actually ordered the TKD3D basically because I had some cash I saved up for some TKD supplies. I'm a very visual learner but have a bad memory. I practice TKD about 6 days a week and am in class 5 days a week. When I'm not in class, I've found TKD3D very handy in helping me remember proper techniques. But! I'm also pretty new with TKD so really don't have much experience in the matter. I've showed this program to others and they have really liked it. I think they did a good job with this program...well, from a newbie's point of view.
