Our family has been playing this one tonight: Geosense.
With this one, you can either register or play as a guest. You can play alone or against someone, and you can choose if you want to restrict the map or play with the whole world. The flash will have a name at the top of the screen, and as fast as you can, you click the point on the map for where you think it is. You get points based on time and accuracy.

We warmed up by playing this one:
www.rethinkingschools.com. That one is a flash of Africa and the Middle East. It is simple - you grab the country name and drop it onto the country.
