a couple of random links

I'm trying to tidy up my Firefox tabs a bit. I'm down to less than 20 now! Serious progress. Anyway: a couple of links

* a very brief video "exploring interaction without touching". Cute.

* Research about domestication and breeding animals for tameness (it's easier than you'd think). Features slightly alarming video of rats from two different lines (one selected on tameness, one on aggression).
