The RPiCluster is a 33 node Beowulf cluster built using Raspberry Pis (RPis) [...] Each of the 33 RPi is overclocked to 1GHz and is running Arch Linux. This demo shows the RPiCluster running a parallel program [..] to control all of the RGB LEDs installed on each of the nodes.

Author says:

Update: While the BeagleBone Black was not available when I started this project, I would have chosen it rather than the Raspberry Pi had it been available. It is the same cost once you include an SD card, but it has onboard 2GB of flash storage for the operating system. It also uses a Cortex-A8 ARM processor running at 1GHz.

'via Blog this'

Create a version of RaspiVid where the frame rate of the camera can be controlled via IPC signalling to a running raspivid process.

Determine which of the USR signals sent by e.g. kill(1) are available for customization of this sort
Define signal handlers for raspivid that set the input framerate NOTE: it is preferred that the video stream not have to be reset when the frame rate is set while raspivid is running
Sequence:
capture frame

run initial frame analysis on first frame
save results
increment frame rate
loop
