Explosion hints with graph editor

Hi,
I’ve found the following tutorial in french that allow the creation of an explosion with particles and use of the IPO editor.
http://blenderclan.tuxfamily.org/html/modules/content/?id=119

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!
