Menger sponge tattoo

Derek van Westrum says

I've had this tattoo since 1990, so you can imagine my surprise/delight on seeing the giant business card Menger Sponge (which I've learned I've always referred to incorrectly as a "Sierpinski Gasket") on boingboing.

The only thing I'd add to the description is the fact that when taken to the limit, the resulting sponge has infinite surface area (it would take an infinite amount of paint to cover it), but zero volume (it can't hold any paint). (Click on thumbnail for enlargement)
