Curvy V-TAP (vertex turning anti prism) is a corner-turning anti prism. The curvy cuts allow the use of a traditional coloring scheme of one color per side. The puzzle has a total of eight axes, one at every vertex of the anti prism. The puzzle jumbles and shape shifts constantly. Internal bandaging has been eliminated, so you can always turn an axis when the slices line up on the outside of the puzzle.
Other Items Needed:
Dye: If you want the puzzle to be black, you can save money by dyeing the pieces yourself with a nylon dye such as RIT or Dylon. Or Shapeways can dye the parts for you at an additional cost.
Stickers: Template available in the instructions forum. If you want professionally cut stickers, I recommend Oliver’s Stickers.
Screws: Eight 12mm M3 pan head screws required, available in hardware stores or on the web.
Springs: Eight springs needed, available in web puzzle shops. I get mine from HK Now Store.
Degree of Difficulty:
Assembly: Inside-out core requires moderate dexterity to assemble.
Solving: Difficult to solve.
The puzzle turns easily.
