Pi Presents is a toolkit for producing interactive multimedia applications for museums, visitor centres, and more.

I am involved with a couple of charity organisations that are museums or visitor centres; I needed a cost effective way to provide audio interpretation of exhibits  and slide/videoshow displays. Until the Raspberry Pi arrived buying or constructing even sound players was expensive. The Raspberry Pi with its combination of Linux, GPIO and a powerful GPU is ideal for black box interactive multi-media applications; all it needed was a program to harness its power in a way that could be used by non-programmers.
