I use this posting for blatantly advertising one of the development projects I was recently involved in – an Android application called Hoccer. It was released by ART+COM Technologies as a free app on the Android Market and as entry for the 2nd Android Developer Challenge.
The aim of Hoccer is to simplify the process of sharing data (currently pictures and contacts) between devices – you use certain gestures for one-to-one (tap) or one-to-many (throw/catch) to determine sender and receiver(s) and the data is transferred over the internet subsequently, so no other mechanism of pairing etc. is needed.
An iPhone version is currently under development, and there’s a web client to hoc data from a desktop computer to a mobile device, so no one’s left out.
