mgo is a two-player Go game for any Java-enabled device (mobile phones and PDAs). It features boards from 19x19 to 9x9, passing, taking back moves, counting of captured stones and territory (with declaring groups as dead), saving and loading of games, walk through of games in review mode, and very easy in-game navigation. mgo_x extends mgo by making use of additional features (SGF export to the mobile's file system) that are only usable by devices that fulfill the JSR 75 specification. Both (mgo and mgo_x) allow for transferring games to the eogban.org Go community service over the air.
Fountain 3D is a little J2ME toy and a technology demo for a custom-made 3D wireframe engine with some benchmarking abilities thrown in. The camera is fully controllable by the user together with the simple particle simulation. The software doesn't require hardware acceleration; all J2ME compliant mobiles are supported.
