Saw one of these used yesterday:

Laser templator

Videos on site.

Used for my countertops, but obviously has other applications, as do the
company's other products, even for...heaven help us...boats.

Never seen a laser templator in action before. Especially useful, the
tech said, for granite. The output goes to a CNC cutter.
