  The implications of brane motion in angular directions of Calabi-Yau flux
compactifications are discussed from the point of view of an observer living on
the worldvolume of the brane and from the point of view of an observer living
elsewhere in the three non-compact dimensions. The brane observer can
experience cosmological bounces and cyclic behavior of the scale factor induced
by centrifugal angular momentum barriers. Observers living elsewhere in the
compactification experience marginally prolonged periods of inflation due to
large angular momentum (spinflation). The presence of spinflaton fields (or
other fields with non-standard kinetic terms) during inflation may lead to
interesting observational signatures in the cosmic microwave background
radiation.
