One of ICHEC's projects at the time was creating demonstration for the BT Young Scientist Exhibition to explain the use of parallel computing. I volunteered to build a Raspberry Pi cluster for this, along with a parallel demo application called Conway's Game of Life. The (very old) code can be found here, and more details about the simulation can be found in the official handout.
The best part of the project was building the cluster. My design placed the 8 Raspberry Pi's into the legs of a plexiglass enclosure shaped like the pi symbol. I also wrapped ethernet cables in colour electrical tape to give them distinct colours, and added several strands of EL Wire to make it glow.
Here are a couple of photos of the cluster and build process.
