A few notes on communication

I was going to write today about how proud I am to be a graduate of Columbia University. The Columbia administration feels that our country is in no way threatened -- and in fact, demonstrates strength and confidence -- by allowing the president of a hostile country to appear on campus and give a speech. (Unfortunately, there appear to be thousands of people in New York who would prefer to live in a country where political speech is controlled and restricted.)

But, I'll spare you the long version of that rant.

Instead, take a look at this video produced by CommonCraft. As blogger Michael Markman points out, the production is low tech...but the communication itself is worth thousands of dollars.
