SeeMore: a kinetic sculpture that's also a cluster computer
SeeMore is more than just a kinetic sculpture. Each "leaf" here is a Raspberry Pi computer node. A total of 255 computers can perform parallel computations. In this video, SeeMore is doing a map reduce search.
As work is distributed to a leaf, it folds out. As it completes its computation, it folds back in. The farther away it folds out, the more intense the processing it's doing. The search results are read out of a monitor beside the sculpture (not shown in this video).
It's mesmerizing to watch and listen to, as the nodes undulate in and out.
