EEG and Cairo

Using the outline in this video:

And an arduino board from a friend, I plan to create a small program that will display the output of the eeg onto the screen.

As my recent kick is with C, I think I'll do that. My current plan is to create a couple different programs, one that handle the graphics and another that will handle getting information from the eeg. That way I can develop  one while I assemble the EEG. I think I'll be using Cairo Graphics or OpenGL not sure which yet, I've selected Cairo because it seems like its easy to work with from the examples I've seen. And then I'll have a memory mapped file, or named pipe between the two programs so that they can share data quickly and efficiently.

Hopefully this all works out nicely, and if I don't manage to assemble an EEG, then at least I've worked with graphics and memory mapped files. Which I think could become a key staple to learning some parrallel processing techniques.
