If you liked Nuit Blanche (or you are interested in modern art generally), you should note that the short list for the Turner Prize 2009 has been announced. The Guardian has a great rundown of the artists on the short list, as well as the Prize in general. The Turner Prize is always interesting and often controversial. Visit the site and wade into the discussion.

Smart People I Know 
The list is well deserved artists that is for sure. Those artists that stay ahead in the creation of new ideas are doing well, but honestly everything or mmostly everything has been done over and over in art, as studying art history has shown us, we can always learn from the old masters.
