For those of you who don't have little kids, GeoTrax is a series of infrared control train sets. You can snap the tracks together to make a little town, all the buildings have some kind of action feature - its pretty cool.
In the past they had just focused on trains and cars, but now they have a cool idea for planes. Now, I know most of you won't care about these, but I thought this was a pretty ingenious way to incorporate planes into a playset. The planes actually ride along tracks controlled by a IR controller that looks like the controls of a plane. I am a sucker for this stuff.
