Hasta La Gadget!

Doormats get a bad rap. They take all the dirt we can wipe off on them,
withstand tremendous weight, let our dogs urinate on them. And when
doormats get very dirty or very old, their owners don’t even bother to
clean them; they throw them away and lay new ones out.  But a South
Carolinian inventor, Andrew Clark, has created a doormat you won’t want
to throw away… because it’s very very smart.
