CSS Heart
(Update 2009-12-07)
I fixed it to work in webkit too.
I was playing with clip and border-radius and put this little guy together.
I haven't tested it in anything but Iceweasel 3.5.5, so your mileage may vary. You can check it out here: CSS Heart.
This is only two divs to make the heart. Much less impressive than the Homer Simpson in CSS.
I suppose I could have just used ♥ huh?
