Video Find(s) of the Day
First you get a Tango Lesson, Number 1. The music is Notas by Gotan Project. I learned about Gotan Project from Tim Harris, whose taste in music intersects mine in a set of positive measure, which fact has alarmed us both.
The second video is actually called Test, if I've successfully exploited Babel Fish to discern the meaning of 測試. It makes me want to see the 1997 movie it's from, called The Tango Lesson.
