Pictures Used in Math

Dan Meyer ponders the perfect math "book" in his blog post The Math Textbook I Would Buy. He wants a series of images on CD that would re-enforce certain math concepts.

One of the commentors mentioned Problem Pictures, you know how much I like using photos, especially old ones. There are some problem pictures on the web but it looks like you'd need to buy the CD to get the full effect of how to use them. Here's a sample problem from the website:

Pile of oranges
How many oranges are here?

A shopkeeper builds a similar pile of oranges but with one extra layer.
How many oranges would this have?

What size of pile could you build with a box of 200 oranges?

Another commentor mentioned Learning in Motion. I love the idea of teaching math using real world examples, wonder if it helps cement the ideas?
