As a continuity to Jin's excellent list, and to celebrate the Forum's birthday from some other
dimension, I am listing puzzles which are not "polyhedra cutting" and/or are based in their
derivatives. I am trying to encourage thinking out of the normal box. And this post is not
interested in the complex inner mechanisms which are the logical extensions of existing polyhedra
cutting puzzles (although many of them are very difficult to make), but in the unique mechanism
concepts which made unique puzzles to become reality.

Presenting the.... *rolling drums*
"Best 20 One-Piece Non-Polyhedra-Cutting Sequential puzzles of Recent Times.I do not wish to list them in a "best order", I think each one has its own amazing structure.
Also, I will not limit my choices to ten, I would rather list all the ones which I believe
are "different" and can encourage the creation of similar or (completely new!) types.
I will let the photos and the videos do all the talking and describing. Searching for each
puzzle's origin/designer, is easy, just use the search button above!

Here we go:
Elementals (early 2007).

Video:
http://www.youtube.com/watch?v=mHziNyeanSsSummary: David Litwin has presenteda very Classy series of puzzles, called Elementals
(and the first of the series was formely called Biohazard). The concept matches the quality, simply irresistible!
Tetrex (2007).

Video:
http://www.youtube.com/watch?v=NCQ_jgC7cY8Summary: 3D folding with strings anyone? This has entered another dimension of puzzles.
Hopefully, someone could follow, there is still potential with Jason Smith's design!
Expansion of the Rubik's clock (2008).

Summary: If you thought the Rubik's clock was wide enough, you were wrong!
A very ambitious design by TomZ, which challenges the complexity of the original puzzle's inner mechanism.
Snakes in a Plane (2008).

Video:
http://www.youtube.com/watch?v=VyTqOVGF_YYSummary: A variant, based on Nob Yoshigahara's rush hour, this time using spirals in a very clever way.
Made by, who else? Oskar van Deventer!
Odd numbered Magics (early 2006).

Video of Throne of Gods:
http://www.youtube.com/watch?v=BrumNWgKRK0Video of Magic Color Box:
http://www.youtube.com/watch?v=fLSacdEg4-MSummary: The first puzzle breakthrough from Pantazis. Not only it was possible to use a closed-loop
odd numbered magic, but the moves and way of solving were totally new! The designs which are done so
far are actually a fraction of all the other possibilities, and have helped to categorise all closed loop magics.
Odd sided polygonal magics (2007).

Video of Iris Diamond:
http://www.youtube.com/watch?v=q6lEBlcmh4gSummary: There was a lot of talk regarding the feasibilty of making odd sided polygonal magics.
The answer to this was a big "yes" by Pantazis. And although kind of restricted, they are very stable
and can move around *all* sides!
Caged 2x2x2 (2008)

Video:
http://www.youtube.com/watch?v=Mpqz3zZAv7cSummary: Alexander Solonenko made this neat 2x2x2 held by an external cage. An idea which may spark
more similar designs.
Lights Out Cube (2001).

Video:
http://www.youtube.com/watch?v=CUUoLWqZhdkSummary: The best of the "Lights Out" series made by Tiger Toys for obvious (cubic) reasons.
A very neat and addictive puzzle, which uses maths in a different way we were used to.
Pyracircle (2008).

Video:
http://www.youtube.com/watch?v=R7kum7o_GDgSummary: Hendrik Haak presented this puzzle at the IPP28 which made many heads turn.
Based on the Panex puzzle (or the Hanoi Tower if you prefer) while adding some circular effect,
makes it one of the most attractive puzzles.
Pachinko (2008)

Video:
http://www.youtube.com/watch?v=Yu3iZDKutCMSummary: Creating a simple(?) permutation puzzle combined with some clever "avalanche" technique
is the perfect recipe for a puzzle which is one of a kind! Made by Oskar van Deventer.
Topsy Turvy (2008)

Video:
http://www.youtube.com/watch?v=H8ZcYvU0sLYSummary: Oskar van Deventer made an implementation of the M12 puzzle, based on the M12 group which is a
"simple sporadic group" of permutations of twelve tokens, and it was published in the July 2008 issue of
Scientific American. By nature, an extremely difficult puzzle to solve.
Number Planet Puzzle (2008)

Video:
http://www.youtube.com/watch?v=koHrrnwvTwoSummary: A mechanical implementation of the Mathieu M12 permutation puzzle, published in Scientific American
and made by Oskar van Deveneter. A puzzle which uses... inverses!!!
Palette and Gear series (2006, 2007).

Video:
http://www.youtube.com/watch?v=cvNMR-a95qESummary: Douglas Engel made some extremely interesting one-piece puzzles based on some new 2D sliding
and rotating concepts. The result was very satisfying.
Astrolabacus (1997).

Video:
http://www.youtube.com/watch?v=hIF0GIpop94Summary: A puzzle out of this world made John D. Harris, and in my opinion, the best mathematical puzzle I ever bought.
Mysterious as an object from an alien culture, yet terrifying as a puzzle. Hide fast, before you become addicted!!!
Brain-chek (2003).

Video:
http://www.youtube.com/watch?v=9XKYOWsd-XsSummary: A puzzle of exceptional quality made by Steven Kunreuther. It has three intriguing levels with a
precision internal mechanism.
Switched Maze (2007).

Video:
http://www.youtube.com/watch?v=l6vFQ-zpLxASummary: At the IPP27 a neat puzzle attracted a lot of attention. It was Kirill Grebnev's award winning puzzle,
which used binary style moves!
Gravity based Flipedrons

Video of Cubedron:
http://www.youtube.com/watch?v=VtKw_sQOMGUSummary: Pantazi's combination of three simple ideas (structure, removal, and gravity), ended up in creating a
series of very intriguing puzzles, which look easy, but they are not! The first of the series is about to be mass produced.
Labyrint (200?)

Video:
http://www.youtube.com/watch?v=4TMxCrVomc4Summary: A puzzle which uses reflection from a certain angle to be solved. Sounds easy?
Not quite, as this is required to be done simultaneously for both sides!!!
(inventor and year information to be added soon)
Brainstring (2003).

Video:
http://www.youtube.com/watch?v=WsFGC1ai7n8Summary: Guido Lap had the excellent idea of making moving string with beads on each end which would overlap
just enough to make everyone's life difficult. Just don't be discouraged when it starts looking like a big string mess!
Crossteaser (2004).

Video:
http://www.youtube.com/watch?v=b6Ipa3fY-SESummary: Rom Dror brought back the Rolling Cubes puzzle to life, with a smart mechanical technique.
A very addictive puzzle which again shows that combination of simple ideas leads to great designs.
Now I should add more, like the C-metrick series, the Curvature of the Ball, just give me some time!

PS. If I have forgot a puzzle, please do not hesitate to add the link(s) by yourself by replying!

I would also be glad to answer your questions, if any arise.
PS2. The braintwist *is* a polyhedron based puzzle, but not so "cutting", as the usage of the
duality concept is simply a new breathtaking way in puzzle making!
