Just had a thought. Right now, Reindeer noses are sold everywhere. This one is lighted.

Could these be used to facilitate head tracking? Might make it as easy as the calibration due to the light?

Having the head tracked would sure add a lot of 'life' to the motion captures!!!

I'm sure these could probably be bought from a supplier year round if there was some demand?
