Software developer Reactrix Systems demoed a system for LCD TVs that mimics the Wii but doesn't require any special controller at CES last week.
IT allows you to make any TV interactive, and coming up with new games should be simple. Reactrix said it only took a month to create the two games shown at the CES and mini-games can be finished in a matter of weeks. It will go on sale later this year and is initially targeted at advertising and public display.
See the system in action by watching the video below.
