I love it! I didn't make everything the right size, but it still looks nice. If you push F11, you can see where I didn't make the background long enough. But, who uses F11 anyway?
I got all the images from Shabby Princess' free DLs, and then I put it all together in Flash. Looks spring-y. :)
If you want to make something like that, I can probably help you with the HTML side of it and image sizing. Those parts were pretty simple.
