Raptor Menu flip Effect

Finally it was the day for playing with the QTransformations and QGV. and the result is kinda nice, but not perfect still . in the coming day's i'll probably make it more functional and put the 3D flipping effect in to more practical use. so basically what I have done is add some basic icons zooming and rotate the QGV around Y axis which make the view flip like magic. video is here : http://upload.ruphy.org/raptor3dflip.ogg
