Whose sonic screwdriver?

I still think that Dr Who has the edge for overall usefulness, but a group at the University of Dundee have come up with their version of a sonic screwdriver. The team used an array to form an ultrasound beam that can both carry momentum to push away an object in its path and, by using a beam shaped like a helix or vortex, cause objects to rotate. The Sonic Screwdriver can be viewed rotating a rubber disc.
