Woodworking and enclosure design look very cool

Very very cool. I love the enclosure!
Sam-------- on HNRPI's have been shown not to scale from a power/heat to $ ratio (I believe Mac Mini clusters are way more efficient), so this is not a practical project by any means. Even so,…

I definitely get the educational appeal. Not just in construction and configuration. This should make a great platform for distributed computing…

Questions
What does the cluster do?
From 1 comment
It looks very cool; what does it do? All I'm seeing in the photos is a cluster of 4 PI's that report their statistics to a dashboard.

Check http://www.pidramble.com/ for a more compact RasPi cluster. Jeff's uSD benchmarks made it to Hacker News front page previously.
