From GCompris

My Nephew Loves this program. He turned 2 in September and loves the train game in GCompris. The first time he opened up the Click Game with the Fish he was laughing so hard it was so great.

I installed Ubuntu Linux for him on a secondary HDD as we didn't want to mess up the main computer, and He loves the GCompris suite, and asks for the games by name, the match game, fishies, etc.
