We’ve never seen a slingshot like this before. This slingshot looks like a typical primitive weapon, but that isn’t what it is all about. Hence the alphanumeric keypad. It will instead tag a building (or several) through the use of SMS.

This digital slingshot was designed by a media group in Berlin. Just type in a message, aim it at a building at fire. Your message will then splatter all over the building. The slingshot is equipped with Arduino, a laser, communications radio and keypad, it truly interacts with the projection system. So your aim matters. Video here.

We Americans will finally be able to get our hands on the Violet Mir:ror home-based RFID reader for $59. It will come with a few Nano:ztags nd three Ztamp:s which will let you specify certain computer functions that will trigger whenever one of the RFID tags gets close to the Mir:ror.

So if you always put your keys on the Mir:ror, for example, it will tell you if your keys are there or not before you leave home. You can get some extra Ztamp:s by the dozen for $20.
