There seems to be currently an interesting exhibition at Foundation Cartier in Paris called “Mathematiques – un depaysement soudain” (a sudden change of scenery). It is a collaboration between mathematicians and artists. The exhibitions english website says that:
Visitors may continue to experience this “sudden change of scenery” via the exhibition catalog, an iPad application, the Fondation Cartier website, as well as by attending a series of events, the Nights of Uncertainty.
I couldn’t yet figure out how one can “continue the experience via the Fondation Cartier website” that is apart from the above mentioned french exhibition announcement and its english translation there seems sofar not so much more online and the flash plugin crashes regularily. But who knows ? – eventually the plan ist that Fondation Cartier thinks of revamping existing websites related to math and art like e.g. the Voro Wiki?
