I have just completed building my computer-controlled calliope powered by my 8 lb Oreck XL vacuum cleaner. The video clip is in RealMedia format and you can watch it by clicking on the link below. During the video, be sure to watch for the Mack sisters, our American Bear, the vacuum cleaner (which you can hear in the background) and the laptop computer that controls the entire performance.
Watch Eric's vacuum cleaner powered calliope play a patriotic greeting!
