I help people make games. On my new site ("Red Blob Games") I post interactive tutorials and guides to game algorithms. On my previous site (Amit's Game Programming Information) I collect links to useful pages about maps, grids, tiles, pathfinding, and AI. On my blog I post experiments and projects and ideas. On my other blog I post my emacs tidbits. I work both on game projects (Wild Shadow Studios - Realm of the Mad God), Root 1 - educational games, Nonagon Games - A Chronicle of Misdeeds) and education projects (Edmodo - online education site, Peter Norvig - interactive textbook version of Artificial Intelligence A Modern Approach).
