Kalyp is a fantasy-based roguelike game written in Java. Its design is based on traditions set by popular roguelike games, especially Nethack. It is single player and runs in a text terminal. The project focuses mostly on the Artificial Intelligence engine for the non-player characters. Most of the game design will be done in scripting, as the core engine written in Java will handle user interface, rulesets, basic actions, and try to hold it all together.
Javasynth is a Java-based system for creating (rather experimental) modular audio systems called sound modules. This allows synthesizers of some kind to be assembled in a modular fashion using oscillators, amplifiers, envelopes, filters, and other components familiar to those that have worked with hardware synthesizers. It includes a separated synth engine and a Swing user interface for building sound modules.
