Kinetic Object

I feel like my mind has been all over when it comes to designing this project. My physical object inspiration was a sandscape. I wanted so badly to incorporate one into a piece but i'm not super sure how that connects to my theme and also not sure if I can make one that A) doesn't leak and B) Looks clean and refined.

My original idea with the sandscape would be that it would be behind a pieced piece of metal, how ever then how will the piece flip around since you dont want metal in the background, so then I was thinking maybe it will have a large boarder and thats where I can put my designs, but it still seemed too straight forward. Its kind of hard to make the sandscape work without using a square or circle. Alas...its just so awesome!!!!

When I was looking into what materials to use in a sandscape I found this pretty cool trouble shooting chart:

and apparently they are pretty much just water and sand with the perfect amount of air to allow movement.

The bottom left of the above picture and the top left of the below pictrure is what I was refering to when I said pierced metal would be in front of the sandscape. 

another idea I had was to have different plaque-a-jour pieces that could swivel and depending on how the wearer had then arranged the colors would be different. (Second drawing on left)

and lastly, I toyed with the movement of a spherical object like a pearl in a riveting "caging" like the drawing on the bottom left of the bottom picture.
