Push Puppet Toy is a computer-controlled puppet that stands to attention when a friend joins an IRC channel or comes online on IM, and collapses when he leaves. The concept is very similar to the Availabot (http://availabot.com/), but works under Linux. Schematics, firmware for the puppet, and plugins for Gaim and XChat to control the puppet are provided.
