Drat. Turns out the USB chainsaw I linked to the other day is not real. Instead it is a promotional idea that seeks to call attention to the wastefulness of printers. The site has now changed into the Papercut site and instead of ordering a USB chainsaw, you can download a program that makes the sound of a chainsaw every time you use your printer.
I guess the idea is to remind you that you are killing trees when you print.
