So I really enjoy progressive drone technology (the field of quad rotors specifically.)
I just came across this video from my university, its the first time i've seen this level of interaction with humans from quads.
All I can think about is walking in a room and getting confronted by a line of quadrotors, that then create a sphere around me, and stab the fuck outta me.
heres an amazing TED talk if you are interested in the technology
