I do some work with this little company out here in Sydney and we’ve released a new product today which might be of interest to you: http://ninjablocks.com/pages/picrust. It marries Arduino + Raspberry Pi + Cloud. It allows you to get up and running with prototypes really quickly. I’ve been an OF developer for a few years now and this has completely changed the way I do physical computing. Hope you guys dig it-- any feedback is appreciated!
