Entry #3340: It's Not Magic, Michael. It's an Illusion.

Everybody thinks that cat videos are an unfortunate product of the internet age, but back in 1894 Thomas Edison thought they were LOL.

The science of illusion. One phenomenon of cognitive bias is called “change blindness”. A researcher stops a person on the street and asks directions. Halfway through the conversation two people walk between them and the researcher quickly trades places with one of them. The target then continues to give directions even though he’s now talking with a completely different person. Most people in this study don’t notice the difference. [Update]: Derren Brown shows you how it works on the streets.

Fresh Guacamole is a very clever animated short.

So: how's the foot ?

Very stiff, but no pain. Meds are good. Crutches suck.
