For those who may be interested

This is an interesting multi-touch capable screen demo. Great for 
gestures, etc. Also would be interesting to see how such an idea could 
be utilized in Croquet.

Another cool thing that could be utilized as Croquet input is the 
SpacePad. There are a few other things in the market but this seems to 
be a reasonable system for experimentation. I am currently assisting a 
project where motion capture is a big part so have been looking into 
many mo-cap systems. Most of them are prohibitively expensive. This is 
not a mo-cap system but can be used as a VR input system.

Also an interesting group of 3D dwellers are growing in a virtual 
environment called second life. I am sure Croquet guys are aware but 
just in case anyone is missing it is an environment worth checking out.
