I want a plamsa cutter. Something I could run off of a power inverter in my truck. I could cut designs in to any metal, like street signs.
Hmmm... I wonder what it would do you cemenet after a good rain storm? If the water would expand fast enough to sort of etch your design into the cement. That would form a truelly long lasting design, given even if they patch it, it would still be rough/cracked at the edge of the patch, so it would still show up through the pain over.
