Playing MindballThought control: Moving a ball via calm brain waves

Talk about head games: Here’s how a fiendishly entertaining diversion called Mindball works. Players sit at a table before a small ball and don a headband that scans their brain waves. The calmer a participant is, the farther the ball moves, with the ultimate goal being to push the little ball all the way to the other side.

Sound weird enough? The game originally was designed as an interactive museum exhibit but was repurposed as a traffic-builder at trade shows.

Mindball costs $1,500 for the first day and $750 for each additional day, plus transport expenses. (418) 826-0018;
