 This project is an attempt to create optimized version of an openFrameworks projection mapping addon for the Raspberry Pi. 
 
-Introduction
-------------
 ofxPiMapper is mainly intended for people who want to use the Raspberry Pi as a cheaper way to create standalone mapping installations. Let's say someone has 10 generative mapping pieces and at last get's an offer to exhibit them in an art or any other kind of gallery. 10 Mac computers? No! PiMapper is here to save you!
 
 The addon itself is intended to be flexible as the separate components of it can be reusable. Use the full version of it to set up your mapping and then switch to no-gui version once everything is set up to save processor power and memory.

-None so far.
