I just saw this website and thought that it was one of the most interesting studies I have seen in a while. It was performed by the government in the '50s to study the effects of LSD on perception and expression. The study involved giving a dose of LSD to an artist and asking him to draw the person who administered the drug. The drawings are posted along with some of the artist's quotes and the administer's observations. The most interesting part is that the drawings don't become jumbled messes like if an artist who was intoxicated on alcohol would draw. These are instead quite creative and expressive. jus thought it was interesting and wanted to share.
