I thought this was kind of cool.

Doug Aitken's "Sleepwalkers" (http://www.moma.org/exhibitions/2007/aitken/)

Projectors are from Christie.

The company I work for did the electrical for the exhibit.....needless to say, it works.

The only thing is that the day before it was opened it was raining so running electrical outside to each projection tower was somewhat of a "wet" experience.
