Promising!
Please (!) keep at it - and more documentation would be greatly appreciated!
(I've considered buying a kinnect as a DIY fullbody-tracking solution, but I have to admit I got confused by multiple reviews complainging over different kinnect versions being better than others and some may be out of production ... ?)
P.S.: This is just an IMPRESSION (!) Could it be the scene is running a little fast? (Or maybe you're just naturally blessed with admirable active metabolism ... ;))
