Night Light

Jean Nouvel has designed the sleekest of stables for the restored horses on Jane's Carousel in Brooklyn.  Simply, he built a glass pavilion (think Paxton) over the attraction to allow for year-round entertainment.  (In summer months, the panes pull back, to allow the occupier of the space to fully access the interior space).
Now for the bomb.  At night, screens are draped across the building's facade and projectors from within the carousel cast shadows of the horses twirling by. Genius.

Beautility

Jean Nouvel's Arab Institute in Paris is at the absolute heap of my utmost favorite buildings. He completely pushed the "envelope". The facade is a calculated grid of perforated steel panes. Perhaps pedestrian, but each small opening works like a camera aperture, dictating light into the indoor space depending on the intensity of the outside light source. The ongoing dialogue the interior and exterior environments share is stunning.
