Elusive Creatures...

I discovered over vacation that my camera has a time-lapse video function. The other day I got a memo under my door that window washers were going to be working on my building. This video is the inevitable result of these two events.

I know the music's kind of cliched but I couldn't think of a song about window washers besides Barenaked Ladies' 'When I Fall' and that was kind of slow and depressing. Any better ideas?
