Sometimes art is about balance

Here at Digital Diner, we are big fans of spontaneous public art forms.  Creating art out of what is available locally in a public place for all to see can be quite cool.  A fellow by the name of Michael Grab has been going around the Boulder, Colorado area balancing rocks in precarious ways to make sculptures.  I've seen similar things around here, but his look quite impressive.  He combines a little geometry and physics and the constant pull of gravity to create these amazing looking sculptures.  They seem to be placed in impossible angles, yet, any time you can get the center of gravity directly over the point of contact, it will balance.  Intellectually, I get that, but still, these particular configurations look quite impossible.
The large sphere of rocks seems particularly difficult because it needs all the pieces together in order to balance.  I see how the end result balances, but I just can't figure out the process to get there.  I think I'll have to give it a try.

Of course, around here in California, the slight variations in gravity known as earthquakes might make such sculptures very temporary.
