'Biotic games' that mimic classic video games have been devised by Ingmar Riedel-Kruse and his team at Stanford. Single-celled organisms are placed in a microfluidics chamber with a microscope camera to track their movements. The image is overlaid on a game board. In PAC-mecium (pictured) the player guides paramecia up and down by changing the chamber's electrical field with a joystick. Paramecia gain points for gobbling yeast cells, and avoiding a computer-animated fish. There's Biotic Pinball, POND PONG and Ciliaball. Riedel-Kruse hopes these biotech games could become part of biology studies and contribute to crowd-sourcing and research. http://news.stanford.edu/news/2011/january/biotic-video-games-011211.html
