Tangible Optical Chess is a strategic chess game augmented with projected lasers and tangible mirrors, to be easy to learn, to be difficult to master, to be strictly strategic with no element of randomness, and to lend itself to emergent strategies that appear after the application of a few very simple rules, rather than have rules that are intended to create certain strategies.
