  Three-dimensional fluids with nontrivial vorticity can be described
holographically. It is well-known that the Kerr-AdS geometry gives rise to a
cyclonic flow. Here we note that Taub--NUT--AdS4 geometries give rise to a
rotating fluid with vortex flow. The Randers and Zermelo forms of the boundary
metrics provide alternative descriptions of the fluid by inertial co-moving or
by accelerated observers. Such fluids possess acoustic horizons. Moreover,
light propagation on the boundary Taub--NUT fluid will encounter an optical
horizon associated with closed timelike curves. In the latter case the Misner
string introduces a multi-valuedness of the scalar fluctuations which can be
attributed to the anyonic nature of the boundary vortex.
