Binocular Skewb is a result of shaping a Master Pyraminx into a cube. The cuts have to be curvy to reveal the middle edges of the Master Pyraminx (they get hidden on the cube if planar cuts are used). Because the first cubic Pyraminx was Tony Fisher's Cubominx, at first I wanted to name it Master Cubominx, but later I though that with its curvy cuts it's closer to Eitan's Eye Skewb. His puzzle has an eye on each face, mine has two - hence the name.
Binocular Skewb is available in my Shapeways shop for
