gplanarity - 17906-7 main

gPlanarity is a puzzle game with the goal to untangle planar graphs for
fun and prizes. If you tend to get addicted to cute little math puzzles,
this one is a doozy.
.
gPlanarity is a super-clone of the flash Planarity game written by John
Tantalo. The original Planarity ran well in IE and Firefox on other
platforms, but was slow and liked to lock up or abort under Linux
browsers.
.
gPlanarity implements gameplay identical to the original Planarity but
adds some UI and game extras around the basic game such as multiple
board generation algorithms, puzzle boards, complete backing state,
group select/drag and so on.
