OpenWIG is an attempt to develop a J2ME mobile application (midlet) with same capabilities as Wherigo player.

Release notes:

Version 0.3.07 has been released. It fixes several minor but important bugs, adds some new Lua properties and supports Internal GPS’s. There are also several usability improvements.

Note: logging is turned off by default, you need to enable it in Options. Important: if you enable logging, then the phone will ask you twice for permission to read and once for permission to write when you start a cartridge. This can be confusing, at first i thought that the app didn’t react to my answer.
