Video Graphic Of RFID In Use

Timo Arnall is at it again, describing RFID technology visually. This video doesn't carry the engineers describing RFID and their process to see the signal as the first video did, but the final piece in the end with the objects making music based on proximity is a lot like the Reactables made a few years ago.



Why are there so many demonstrating the technology, and none actually building and selling it?
