From the video notes:
This project investigates chiral self-assembly with many parts in order to explore the aggregate behavior of simultaneous assembly and self-selection. 240 pieces are agitated to self-assemble closed molecular structures. The continual process shows the various stages of assembly from independent parts to fully assembled structures.
This work points towards a future of both tangible educational tools for scientific phenomena as well as new possibilities for industrial-scale assembly.
Skylar Tibbits has some pretty awesome stuff on Vimeo. This one is beautiful:
