These are my 3z3z3's. The top one is a cube from the 1980's.
The left cube is from 2004. The silver faced cube on the right is a 25th anniversary cube.
There are 2 different 25th anniversary cube styles. An earlier one was released,
but I don't have a photo of that one. The one above is the 2nd style.

The Rubik's Revenge.

The 5x5x5 Rubik's Professor. My favorite cube overall.
The cubies on this cube are quite small when compared to a standard cube.

Alexander's Star is a 12 sided puzzle from the 1980's.
This puzzle first came with stickered sides like the Rubik's Cube,
but since the pieces rub against the stickers, they would peel off.
The puzzle was updated with painted faces for more durability.
The one in the picture is painted.

The Bart Simpson head is a 2x2x2 puzzle. The puzzle is not the easiest to turn.

The Missing Link was one of my favorite puzzles as a child.

The Orb is actually split down its vertical axis and rotates on that.
The beads are then moved around the different rows. An easy puzzle to solve.

A Tomy Pyraminx in original case.

A dollar store pyramorphix clone. Made of cheap, thin plastic. Turns horribly.
This puzzle changes shape though as seen below.

The Rubik's Triamid was nothing but a bad idea. It is too difficult to move the pieces around.
The idea is to remove a 4-piece pyramid from the puzzle, rotate it and put back on the other 6 pieces.
Then remove another 4-piece pyramid and repeat the process. The pieces will come apart and it hurts the hand.

The Whip-It has to be the easiest puzzle ever. Not much fun at all.
