Well, technically there's nothing really super about this. I mean, knocking together systems using software to link them all together to perform larger calculations and work through heavier data sets has been a thing for ages - Folding@Home, by my reckoning, may even be the largest supercomputer on the planet, from a technical standpoint if you add everything together. But what's different about this supercomputer is the components that make it up - 64 Raspberry PI boards are knocked together using a Lego frame and networked together to do some low-level crunching.
