Liam is obsessed with Phun, a free physics game. He’s been working on making a Hummer for a few months now. Here is the screencast. Sorry can’t figure out how the audio works, which is very sad because his voiceover was so confident and precious. Talking about creativity and how he hopes it will inspire others to build on it. Hmmmm, sounds like mom! Parenting victory!
It’s so good I asked him if really he made it himself. Several times. Soon this child will pass me by. Maybe he has already.

Is he actually adjusting the tension on the shocks in that screencast?
Liam says he is just demonstrating the shocks.
