Art imitating life (T-1000, anybody?) or yet another evolutionary step towards the subjugation of mankind? For now, let's just shift focus to the immediate and soak in this novel feat of robo-replication engineered by a team from M.I.T. Headed up by Professor Daniela Rus, the Smart Sand project looks nothing like it sounds and that's because the tech in question is currently more cube than grain. Measuring 12mm per side, these intelligent pebbles work in unison to recreate an object by first surrounding it and then building a shared 3D map that's used as a blueprint for duplication.
