The Cutting Begins - To Create Folds

I highly doubt this is how nature develops brain folds, but my Dremel was happy to participate.  Sadly, I went through three Dremels in the process of carving the cranium.  This is certainly usual - two of them were returned due to faulty wiring.  The final one was my gem and has worked overtime for me.  Despite that, this is the beginning of the brain taking shape.  Diamond cutting discs are a gem.  Expensive but a gem!  Eating through limestone like nobody's business.
