Black or White, designed by Vesa Timonen and Tomas Linden. This took me an amazingly long time to solve, considering that it's relatively simple (but non-intuitive).

Urchin; balance the Urchin on the block of wood; little bit of a gimmick on this one. Periscope; remove the metal ring; a not-too-difficult solid disentanglement, but it looks nice and has a satisfying solution. Total weight; 1 lb 7 oz.
