cool crabs

I've been thinking a lot about what Jesh mentioned on his blog about walking down the stairs backwards and learning from children (you'll have to read it : ), which got me thinking about these crabs that put all that work into their balls of sand. Its like you can see that some of them love designing and create neat little shapes and lines, while others just think its work and dump all the sand in one big messy pile : )
hmmm....
