Ha - we have been generating an extremely large rock collection for several years. This spring DD3.5 has gone nuts with collecting rocks. And she wants to wrap them as gifts too. She is also quite into maps and globes right now.

Kriston - you'll appreciate this one. As a summer project for DS7, we are going to build a time line and mark up a world map for all the world wonders, technologies, leaders, cities, from Civilization 4. Maybe build a mini reference.
