So a very interesting post went up on Franco Vescovi's Instagram page! It showed a "Tesla Vibration Sequence Motor Technology" machine. It's clearly a 3D model but talks about the power being in the grip so there's little to no machine attached to the grip just a power cable. This obviously dramatically cuts the size down so it won't be far off just using a normal marker pen instead of the much longer "pen" machines we have now. Exciting times ahead. Great to see builders constantly pushing the envelope!
