We first released a wooden version of Slump Cube back in 2010, when Eric had this to say about it:"This puzzle was inspired by the 3x3x3 dovetailed cube that Wayne produced a few years ago. With permission and a little advice I decided to look into reproducing the design. I quickly realized how many possibilities existed in the 3x3 format, and decided to start with a 2x2. I brought Ronald in because his burrtools kung fu is far superior to mine...lucky for me he was in a design slump, so he pick...

"Stewart Coffin's Nova #8-B. Six pieces assemble in two halves to form the second stellation of the rhombic dodecahedron. A step up from the regular Nova, this puzzle uses the color symmetry of five different wood species to create a more puzzling puzzle! Still not terribly challenging but the wood choices make for a nice display piece." This copy is made of multiple rosewood varieties. It looks and smells beautiful!
