I finally had the chance to play around with xtranormal.com. It's pretty addictive. You can make a machinima movie very quickly (once you learn how to deal with a few idiosyncrasies). I would recommend steering clear of the "Take 5" button, as it pretty much ought to be relabeled "trash my video".
If you aren't familiar, there is a subculture of "premise technicians" (technicians that go on site to make repairs), for certain well known cable and telephone companies. It's not a rewarding job. There is a raft load of satirical videos on Youtube, using xtranormal machinima, in the format of sort of "a day in the life" of a prem tech.
So, with that as my inspiration, here's my first piece. Yes, this is based on a true story. Some liberties were taken, and the names were changed to protect the guilty. Audio track is NSFW.
