Conveniently, he already owns an eyepatch

Stellan's bedtime very late tonight because he asked me to explain how his 3D glasses work. A, how can you not respond to an earnest request for knowledge like that, and B, it turns out 3D glasses are pretty complicated to explain. I think he got the binocular vision part, but I lost him on the red/blue color filtering; I'll have to put some demonstrations together for tomorrow...

My biggest failing as a parent is over explaining. I'll be halfway through a disquisition on torque and inertia and will finally realize he's lost interest in the sit 'n spin, he'd like a peanut butter sandwich now. But this time I kept checking in with him, he really wanted to know how it worked.
