Although 90% of my collection is made up of metalic disentanglement puzzles that aren't included here, these are a few of my favorites that I have gotten a hold of. I try to have all different types and not just the same of one thing.
The original Rubik's cube with different shades of black, grey and white.
A cube covered with sudoku-themed stickers.
The 2012-version of the Void Cube.
CUBE (SHAPE CHANGING)
Get back to Square-1
An american based version of the Square-1. It distinguishes itself from the other variants because it was sold in scrambled state.

SIAMESE & FUSED
The original version produced by Politoys.
An electronic-based multi-game-object which looks like the puzzle that started it all.
Twist and slide the top face of the cube to move the lights until you reach the solution.
Six coloured balls have to be moved in their matching domes.
Try and remove the inner sliding mechanism, blocked by knobs you can only turn one at a time.
The object of this puzzle is to get all the sliders either in or out. Several stacked and slotted disks inside the puzzle limit the range of movement at each step.
