DESCRIPTION:Direct detection\, and direct spectroscopy in particular\, hav
 e great potential for advancing our understanding of extrasolar planets.  
 In combinations with other methods of planet detection\, direct imaging an
 d spectroscopy will allow us to eventually: 1) fully map out the architect
 ure or typical planetary systems and 2) study the physical properties of e
 xoplanets (colours\, temperatures\, etc) in depth.  I will discuss in part
 icular the constraints on the distributions of wide giant exoplanets place
 d by the current generation of direct imaging surveys.  Variability attrib
 uted to cloud structure already appears to be a persistent feature for L a
 nd T type field brown dwarfs\, potentially due to the breakup of thick sil
 icate and iron condensate clouds during the L to T spectral type transitio
 n.  Directly imaged planets occupy the same temperature regime as L and T 
 type brown dwarfs and are likely to be equally variable.  I will also disc
 uss the prospects for detecting and characterising exoplanet weather patte
 rns through monitoring the intrinsic photometric variability of these obje
 cts.\n
