  We analyse the dynamics of a probe D3-(anti-)brane propagating in a warped
string compactification, making use of the Dirac-Born-Infeld action
approximation. We also examine the time dependent expansion of such moving
branes from the ``mirage cosmology'' perspective, where cosmology is induced by
the brane motion in the background spacetime. A range of physically interesting
backgrounds are considered: AdS5, Klebanov-Tseytlin and Klebanov-Strassler. Our
focus is on exploring what new phenomenology is obtained from giving the brane
angular momentum in the extra dimensions. We find that in general, angular
momentum creates a centrifugal barrier, causing bouncing cosmologies. More
unexpected, and more interesting, is the existence of bound orbits,
corresponding to cyclic universes.
