Casttoo — Waterproof X-ray cast tattoo

"Send us the digital file of your x-ray,

and we'll send you back your break in print,

ready to be applied directly to your cast."

The creators call it "Happy healing,"

and claim it's the

"most innovative, fun thing to hit the field of orthopedics

since the introduction of colorful casting tape."

I won't argue.

Plenty other designs,

some of which are pictured above and below,

for those not into sharing on quite so intimate a level.
