It's your choice how to explore Gemini and align with the various factions, earn your money as a merchant, bounty hunter, traitor, or pirate.

Booruatsukaigaumai is a one-key desk game using OpenGL 3D scene rendering. Your task is to guide a number of red balls through 6 different levels full of blocks, holes, and gates. You have to make the balls go through as many gates as possible, which earns you the score points. However, you only have one key to control the desk tilt, which makes balls roll to the right (when the key is pressed) or to the left (when the key is released). Any other movement of the balls is controlled only by gravity and interaction with blocks, holes, and other balls. Even if the principle seems to be very simple, the game can be quite challenging.
Micropolis is a city simulation game engine based on the original classic SimCity source code. Micropolis is based on the Tcl/Tk version of SimCity. It consists of the micropolis module, which is the engine recast as a C++ class; the cellengine module, which is a cellular automata machine engine; and the tileengine module, which is a Cairo based tile renderer. It is intended to be used with the OLPC's Sugar user interface environment, but layered so the core code is useful in other contexts.
