I think I may have finally seen it all.
''What do you do when you want a tattoo but don't want the commitment of permanent ink? The moodInq system is a breakthrough in tattoo technology, using a skin-safe proprietary E ink encapsulated pigment system that lasts a lifetime but can be configured to display any design (or none!) to suit your mood. So how does it work? We have partnered with leading physicians and technicians in the cosmetic surgery industry to implant the E ink grid, called a canvas. The canvas can go anywhere on your body and be configured to the size and shape of the body part you'd like to ink. After a short healing period (usually 2-3 days), you can begin using the moodInq software included with your kit to change your canvas to display the tattoo you desire!''
