Trimphone, http://rmx.cz/trimphone/ is my real experiment with arduino and you’ll find all details on the page above..

Basically, I got this idea of creating a tangible video mixer made from old phone with rotary dialer, so I went eBay, found this appropriate looking model, bought it and ripped guts out of it.
Then I spent quite a lot of time on the ear footage (I’ll put some mixed showreel up soon) - I used Cinema 4D for 3d compositions and After FX for the rest.
From my observations how people interacted with it, they mostly enjoyed the camera build in the ear piece as it brings some surrounding elements (like their own faces) and “direct interaction” on the screen, and they often even didn’t try to dial up different footage, as they probably thought it’s all about the camera.. :)
