Screencast and tutorial

I made a short screencast and a tutorial about good exercices that everybody can do in blender… Bellow the tutorial screenshot and the link to the screencast:

Vinicius, great tutorial, and cool effect, i liked it a lot. :slight_smile:

I wonder if it’s possible to make one of the cubes roll towards the camera and stop in a exact position.
Place a logo or text on it and it stops perfectly framed in front of the camera, that would be a nice intro.

Anyone know how to make that?
