As much as this would make for a nice concert/show gizmo, I'm also interested in those tiny helicopters themselves. To control them with such precision would be impressive (well from a non specialist point of view). Yet I can't seem to find info about them on either of the labs' sites (this one and the ARES lab). There could be many other use for such swarms (I'm thinking controlling a local set of cameras to get different angles, but I'm sure there are so much more).
