::MY EXCUSE FOR NOT STAYING OFF THE GRID::
I'm a huge fan of IBM's
TryScience, a website that encourages kids and grown-ups to explore science through different experiments (via virtual-reality or reality-reality). They've got tons of different science arenas to play around in -- plus an "adventure," an in-depth look into the science of a real-world problem. They've got a new one up called
The Grid, and I've played through both the online games. (I'd've beat both, but I didn't solve the aliens question... Is it solveable at all?)
I keep hearing "Hack the planet!" in my head now.
