The 13 most WTF gadgets

Speaking of tattoos, if you're not into the whole "permanent" part of it? MoodINQ is the answer for you!

Step one: Get a surgeon to implant an e-reader screen under your skin.

Step two: buy the $150 moodINQ wand and a subscription to moodINQ's tattoo database.

Step three: choose a design, and rub the wand on your skin. Presto! Instant (sorta) tattoo!

Or you could just buy a Moto X.
