Software
Here are some of the programs I have written in my spare time. Feel free to download and share them; they are all open source.
Tic Tac Toe
Download from BitbucketDescription: A simple implementation of the classical paper-and-pencil game, featuring an invincible artificial intelligence (AI).
Implementation details: The AI uses the Minimax algorithm, leading to a perfect play. Therefore, the player cannot possibly win; the best outcome is a draw.

Voxel Terrain Generator
Download from BitbucketDescription: An experimental terrain generator for a contest at StackExchange.
Implementation details: A heightmap is generated by a random walk and then displayed as a collection of cubes with WPF 3D.

Lyreword
Download from SourceforgeDescription: A powerful and flexible word generator, including templates, machine learning and anagrams.
Status: Unfinished. Currently on hold.
