Want to annoy IronJungle? Tweet a bunch of commands to his Twitter Robot Hand! His hand is monitoring the Twitter stream using a Raspberry PI and will act on your commands (seen below).
 “A Raspberry PI monitors the tweets to @OurCatDoor. The PI’s GPIO acts as inputs to a PICAXE 18M2 which controls five servos on a robot hand.
You can control the “The Hand of PI” by sending a tweet to @OurCatDoor.  Ifyour tweet includes any of the text below, the “Hand of PI” obeys your command.
Valid commands are (lowercase):
one (holds up one finger)
peace (shows the two finger peace sign)
three (three fingers up)
hookem (if you are a Texas Longhorn fan this one makes sense)
fist (the Hand of PI gets ready to fight)
open (ready for a ‘high five’)
finger (well…Â this will be the most tweeted command)”
