Explosion hints with graph editor

I’ve found the following tutorial in french that allow the creation of an explosion with particles and use of the IPO editor.

the problem is this tutorial have been made with an old version of blender (2.4) and the graph editor was the IPO editor. With the 2.66 I just can’t figure how to do the same thing with the graph editor…

I search a good tutorial to make the same thing (explosion by modify the colors of materials with graph editor) as the tutorial of the Blender Clan.

thank you!
