Transgenic Sting Ray Shoes
Best case scenario, it's shoes made of fake leather. Worst case scenario, a con.
Update, 12/22/12: Yep, I called it! It's a hoax.
So here is a thing which is - I would estimate - at least 93 percent fake.
Rayfish Shoes is a company based in Thailand which lets you choose the crazy-pants color and pattern you want, then injects the necessary genes into a stingray fetus. When the stingray grows up to shoe size, Rayfish harvests the stingray's leather and boom: transgenic shoes with the wacky pattern grown right into the skin!
The claims of being able to custom design skin color patterns (like fuchsia leopard print, or acid yellow zebra stripes) is patently false. Not only is this not possible with today's technology, it's probably not possible at all, ever.
