All Those Little Rocks and Shells

I have a thing for rocks.  Ever since I can remember.  So when we get away anywhere invariably I come home with pounds of rocks.  Some of them are wonderful specimens, but tiny and likely to get lost in the flowerpot dirt that usually becomes their destiny.  But recently I gathered up the tiny collections from our trips to Drumheller, and Yellowknife.  I enlarged pictures to 5'' by 5", and used shadowboxes to display the photos behind the mat, and the rocks in front.  I could see this working with tiny seashells; guess we just have to go back to the ocean so I can do another.
The rock on top of the top picture is a polished geode I bought at  a rock shop.  I like it there.
