Child-rearing.
That's actually kinda close. Long story short, I am planning to do an art installation of a robot that learns from it's environment.
ADDITION: The more I think about it the more I'm sure my sister had one back when we were kids. Not that that really helps any, but it does date the toy to the late 80s/early 90s.
ADDITION2: My sister just emailed me back and recognized it from a home movie shot one Christmas before we moved to Korea. So like really really little, before elementary school. That would be early to mid 80s.
I'm starting to think maybe I should use a modern toy that has a similar look, because something from that long ago will be pretty impossible to find.
