BerryIO by Daniel Bull. As demonstrated to me at the Milton Keynes Raspberry Jam Sept 30th 2012.
Apologies for the high background noise level. This was shot live at the event, so we couldn’t ask everyone else to shut up or we’d have been lynched. ;)
If you want a closer look, you can download Berryio from here http://frozenmist.co.uk/downloads/berryio/
In a nutshell, it’s a web browser based IO control system for the Raspberry Pi.
