Arduino-based Curtain Automation

Jamie Zawinski uses a command line to control his curtains..

..How cool is that? 

How does one just wake up one day and think, - "Hm, by automating my curtains, I could save 5-10s of walking time to the window and a few jaules of energy per morning... To the construction desk!!!"

Well, I am assuming this is exactly what Jamie did when he decided to hook up some motors to an arduino board in order to control his curtains via command line.
