What is it like being a geek? It means being surrounded by opportunities to teach, even at the dinner table.

One of the LEGO magazine issues had included a pair of 3-D glasses. The issue had been tossed out due to a large number of jam stains, but the 3-D glasses were still on the kitchen table.

I put the 3-D glasses on. Things around me shifted from red to blue-green, depending on which eye dominated that part of my mental picture. I could influence which color I saw at a point by mentally favouring one eye or the other, but I couldn’t get the scene to be one colour unless I closed one of my eyes. Interesting.

I explained my observations to W- and J-. Curious, J- borrowed the 3-D glasses and put them on.

“Cool,” she said, looking around, as I told her about eye dominance.

Then I took a red pen from the pen holder and rolled it towards her.

“Wow! That looks white!” She switched eyes. “Now it looks black!”

Then I showed her a blue pen. She tried looking at the pens with both eyes, then with one eye, then the other.

W- and I explained a bit of colour theory along the way.

What is it like being a geek? It means recognizing that every little thing has a mystery that can be unfolded and explored.
