I wish i had the knowledge to create something as beautiful as this. The project Mark created allows him to tune in to twitter posts in real-time using the analog radio. You can use the knob to scan “stations”, which are different twitter posts. Amazing, amazing, amazing.  He used an arduino board and lot of grey matter at SARc.

Also, here is an interesting programmatic response to Mark’s project which integrates twitter and youtube. TwiTV click on the top right black square to flip channels. Graphics are kinda shabby though.
