Since 1990 I have been a full-time independent designer of visual puzzles and games for the web, computer games, magazines and toys. My puzzles are in the spirit of Tetris and M.C. Escher - visually stimulating, thought provoking, broadly appealing, and highly original. I have created hundreds of puzzles for magazines, and thousands for computer games. I am especially interested in daily, weekly and monthly puzzles for the web and portable devices.
