During 34C3 hacker congress I met this wonderful creature and its creator. Powered by a high-pressure airline, kindly provided by Messe Leipzig, it could locomote and express itself using a number of pneumatic actuators whose solenoid valves were interfaced thru a 16ch relay by an Arduino.

After a few day of glorios marching the “PLZ kill me” mode was announced by the author: everyone was allowed to reprogram the bot using the relay channel pin mapping, published along. Among others I spent numerous hours writing choreographies for this immortal piece of art.
