„Phun“ už víc jak rok neexistuje, binárky už jsem na webu autora už nenašel
To, na co odkazuje článek je „Algodoo PHUN edition“, který sice umožňuje navíc věci jako tvorbu ozubených kol, ale za to se přiliš dlouho načítá, je pomalejší a jiné užitečné fuknce (trvalé zakázání mraků) zmizely.
Zbezny pohled do Wikipedie rika neco jineho:
Phun is a 2D physics engine created by Emil Ernerfeldt for his master thesis while he was studying at Umeå University in Sweden. It is based on the Constructionist learning paradigm, and free for non-commercial use. On May 15, 2008 Phun was taken over by Algoryx Simulation AB, where Emil continues his work on the program.

Phun Beta 5 was renamed to „Algodoo: Phun Edition“ after Phun was taken over by Algoryx Simulation AB. Algodoo is now available to the public for a fee, and has already been made available for the Intel Classmate PCs [2] and demonstrated at the 2009 BETT event in London [3][4]. Beta 5 work is now complete, and is available at phunland.com.
