My humble collection
CUBE (SHAPE PRESERVING)
A 2x2x2 with a twist that defies all attempts of classifying.
CUBE (SHAPE CHANGING)
Fisher's Golden Cube
All the stickers on this 78 mm modified Skewb are the same reflective golden colour. There is only one solution.
A midturn 3x3x3 still in hexahedral shape but with such an awkwardly oriented axis system that every piece is uniquely shape and therefore sticker can be unicolored.
A face-turning dodecahedron with a mixture of pieces from other puzzles with this axis system.
This is a newer version of the Megaminx, published by Meffert, with tiles and 12 distinct colors.
