Scanned aspen leaves

Here are some of the scanned leaves that I collected at the cabin. As you can clearly see, they change from green to yellow to red to brown. I love them. (Also, I took the time to upload these REALLY high res, so please please click on the photo to see it large!)

All the colors, arranged in order of how they change.
Looks like a flame, doesn't it?
