The concept of the Dattoo arose in response to current trends towards increasing connectivity and technology as self-expression. To realize a state of constant, seamless connectivity and computability required the convergence of technology and self. The body would need to literally become the interface. Computers and communication devices require physical space, surfaces, and energy. The idea of DNA tattoos (Dattoos) is to use the body itself as hardware and interaction platform, through the use of minimally-invasive, recyclable materials.
The picture reminds me of the Buzz Lightyear/ Turanga Leela style forearm computer. That seems like a pretty practical place to put a Dattoo. I have a few other ideas:
Put a Dattoo on the palm of your hand, for more interesting waving and "talk to the hand" gesturing.
On the bicep, for wearing your Facebook status/latest tweet on your sleeve.
Upside-down on your stomach, for the world's most entertaining navel gazing.
Dattoos are a long, long way off -- it's currently just a concept design, not a technology plan -- but I can imagine artists like Lady Gaga and Marina Abramović coming up with crazy ideas for installations and projects. Or, you know, it could be used to make people healthier, I guess. My daily subway commute would sure be even more colorful. Can someone make this happen, please? Image via FrogDesign.com
