We see a lot of mashups (our directory lists over 4,300 mashups). Lately we've noticed that they've moved beyond your ordinary application. Here is a quick overview of some recent additions that are fun and useful.
BlindSquare founder, Ilkka Pirttimaa, once browsed over Wikipedia's Augmented Reality article and realized the concept focused solely on vision. Pirttimma believed the concept could expand to audio; thus, the idea for BlindSquare was born. The BlindSquare app provides "a new solution that combines the latest technology to help the daily life of the blind." BlindSquare pulls data from the FourSquare API and alerts users of restaurants, stores, and other locations surrounding them via audio instructions.
