Anyone who thought video games were a waste of time have probably been surprised about Nintendo's latest and greatest, the Wii. It gets people active by using their arms and motions to simulate sports such as tennis, baseball, even bowling. But it doesn't stop there! A new useful application is emerging: surgical training.

Resident surgeons were found to perform better on simulated operations after playing a bit of Wii than those who opted out of the fun. How much better? They scored nearly 50 percent higher on tool control and performance.

Of course, not all games are going to improve coordination. Games that require subtle movements and precision are obviously better than those that require you to swing a bat. But this approach could be a very valuable medical training tool for countries which can't afford higher-end solutions. They are developing special software for the console, which costs only $250, that could hone surgical skills even more. Imagine bringing home your own copy of "Surgery 101" in the future!
