Handheld Router Only Cuts Where Needed for 3D models

I seem to be on an MIT kick today.   This time its a router that has a sensor in it to know when to “cut” when a user is holding it to build a 3D object.  This is a nice solution and reminds me of what could be next after Shopbot’s “Handibot” for consumers/hobby folks.
