Here are some of my favourite and interesting cubes or twisty puzzles i have seen.
Oskar Van Deventer's 17x17x17: The 17x17x7 is the worlds highest order cube puzzle (has the most layers in a cubic shape). The 17x17x17 is a 3D printed puzzle designed by Oskar Van Deventer. The next biggest cubic puzzles are the 13x13x13, the 12x12x12, and the 11x11x11.

Matt Bahner's Yottaminx: The Yottaminx is the worlds highest order twisty puzzle (has the most layers or pieces not in a cubic shape). The Yottaminx is a 3D printed puzzle designed by Matt Bahner. It is next in the line of !minx" puzzles after the Zetaminx.

All "Minx" puzzles: There are 12 puzzles in the dodecahedron minx line but a lot of other puzzles have minx in their name but aren't a dodecahedron puzzle.In order of size,smallest to biggest, the minx puzzles are the kilominx, megaminx, master kilominx, gigaminx, elite kilominx, teraminx, Royal kilominx?, petaminx, examinx, zetaminx and of course the yottaminx.
(just a few of the minx puzzles. Flower/kilominx right mid, Megaminx right back, Gigaminx left back, Teraminx left mid & left front, Petaminx right front.)
All gear puzzles: The cube was originally designed by Oskar van deventer and mass produced by mefferts. Many different gear puzzles are now available including the original gear cube, the gear shift, the gear ball, the gear barrel and many many more.
