Hi Shapeways fans, Sixth Sense Huge is a huge version of the Sixth Sense puzzle ring, meant as big demo model. This six-part puzzle ring is a design by Bram Cohen, and developed by Oskar van Deventer. It is a "size 190", with an inner diameter of 60 mm and an outer diameter of nearly 90 mm. A solution was worked out by Daniel Danzi and D=D=, two puzzle-ring enthusiasts from Virginia, USA. Watch the YouTube video. Watch the solution video. Buy the puzzle at my Shapeways Shop.
