Those who tuned in to the Nokia event last night would have seen that Panagraph was announced (by Stephen Elop himself!) alongside Flipboard, Path, Vine, Hipstagram and others coming to Windows Phone. It will be a Nokia Exclusive app :)
Basically it lets you create Hockney inspired photos, utilising the new Nokia Lumia 1020 (with a 41 MP camera).
