Playing in the sand...
 

This is really awesome to watch this lady. At first you are'nt really sure what your looking at, but give it a minute and you will be amazed by what she creates. Just know your looking "up" from the bottom of the box. You'll see what I mean. It really is worth taking a minute or two to see what developes. She makes it look so easy!!
