6. KDE remade KAtomic from Atomix, and distributed it under the terms of the GNU General Public License (GPL), Version 2. The source code can be found at KDE
   Atomix is a puzzle video game developed by Günter Krämer (as "Softtouch") and published by Thalion Software, released for the Commodore Amiga and other personal computers in late 1990. The object of the game is to assemble molecules from compound atoms by moving the atoms on a two-dimensional playfield. Once you push an atom in a certain direction, it will move until it hits something that makes it stop, which could be a wall or another atom. This behaviour is exactly what makes playing it not trivial and, therefore, fun, as you need to think quite a lot about how to have your molecule organized.
   I did not use any level design from Atomix, since these remain the intellectual property of their authors, Softtouch & RoSt. All level desgin comes from KAtomic, and licensed by GPL.
   To know how to play this game, please reference Finding Optimal Solutions to Atomix.
7. Ignacio Pérez Gil remade Deflektor X4 game, and the Deflektor developer Costa Panayi endorsed the creation and distribution of it in the 2000s.
   Artsoft Entertainment remade Deflektor(C 64) and Mindbender(Amiga) as Mirror Magic, and source code released under the GNU General Public License.
   Deflektor is a puzzle game developed by Vortex Software and published by Gremlin Graphics in 1987. In this game, the player has to rotate mirrors to deflect a beam in order to destroy all the cells of each level. There are also other devices the player has to be careful not to touch with the beam for too much time because otherwise the system will overload.
   I did not use any data and graphics design from original Deflektor, since these remain the intellectual property of their authors. All level desgin comes from Mirror Magic, and licensed by GPL2.
8. Piotr Migdał created an open source project: Quantum Game - a puzzle game with real quantum mechanics in a browser. It is a little bit hardly to play in iPhone, so I remade it to run as a native App in iOS platform.
