  We present a three-dimensional steerable optical tweezer system based on two
pairs of acousto-optic deflectors. Radio frequencies used to steer the optical
tweezers are generated by direct digital synthesis and multiple cross beam
dipole traps can be produced through rapid frequency toggling and time
averaging. We demonstrate production of arrays of ultracold atomic clouds in
both horizontal and vertical planes and use this as an indicator for the
three-dimensional nature of this optical tweezer system.
