This video is circulating the Internet today. It shows an unnamed artist making a portrait of Conan O'Brien out of cheetos. Allegedly, he (she?) used about 2,000 cheetos from 50 bags for the work, but the provenance on that information is iffy.

UPDATE: In the comments, mikerbaker provides a link that informs us that this was created by artist Jason Baalman, and that it measures 5 by 4 feet. Thanks, Mike!
