We'll see how that plays out as they age, which tends to include things like getting married, having kids, buying a house, and that kind of thing. For instance, our garage now contains 2 strollers, 2 kiddy scooters, 3 kiddy biycles of varying sizes, and one sort of push-tricycle thing. I didn't have all that crap when I was younger, either!

I heartily agree with the advice elsewhere to look at "boring" and "unsexy" stuff. It also helps if it's "far from the tree" in the sense of not picking something that's immediately related to the world you know as a programmer.
