YouTube user Thretris modified an original NES with a custom Tron paintjob, and stuffed in some new hardware. Skip to minute 2 to avoid the technical stuff.
This NES has been custom painted using a hand mixed airbrush paint with glowing powder. The paint job not only glows BRIGHTLY in black light, but it charged and stays glowing on its own. The console also has NESmod installed which acts a dual mono "stereo" mod with boosted sound from an additional PCB with amplified audio.
Thretris has also customized a Gameboy.
