Franken-Gogh's ear floats eerily in a hermetic box and is kept 'alive' by a network of hoses and fluids. And guess what? The damn thing can actually hear, thanks to a microchip that stimulates nerve pulses.
No mention if Strebe plans to grow the rest of Vincent back...that would probably be wrong though, right?
