I've long thought that roleplaying games would be an outstanding tool for museum programming and it turns out that some other visionary thought so, too, and actually made it happen.
The Royal Ontario Museum is hosting a Saturday morning D&D campaign for kids 11-14 years old, which utilizes material from the collections to teach kids about myths, monsters, and weapons of ancient cultures. Talk about a great way to bring history alive! I wish something like this had been around when I was a kid.
