This is a beautiful designed Advent Calendar with OpenGL Effects,
see what cool effects can be done on the iPhone/iPad day by day.
See 3 Dimensional Galaxies, and great stuff each day.
These are not just simple images, these are moving particles!
A really great show you should not miss!
Behind some doors your interaction is needed (tap the screen,etc...)
Also with some christmas music.
I hope you will enjoy it
