Leeching forums is great but sometimes we have to share :
A photo/video slideshow who follows kinect users in 3D world.
(max 6.1 with dp.kinect)

Featuring a gesture control to navigate thru items !
A hand along the body, a hand pointing high enough
(look at subpatch to understand the position),
a little OpenGl scroller appears and you can choose your picture in the x axis !

I did some optimisations but I encourage people to extand them.
