CROWDED, hot, boring: commuting is rarely enjoyable. Interactive games might help make your journey pass more quickly and pleasantly.

Chad Toprak of the Exertion Games Lab at RMIT University in Melbourne, Australia, and colleagues have developed a game called Cart-Load-o-Fun that can be installed on buses, trains or trams.

"Back in the 70s we had games arcades," he says. "People would gather and a community would build up." But today people play games either at home or in a private bubble on their phones. Toprak wants to put games back into public space.
