My entry for the wedding contest: a Sierpinski tetrahedron made with hearts instead of triangles. It could be used as a centerpiece, maybe decorated with some flowers, or as a gift.
Either way it may be personalized with the names of the couple in the big hearts.
Inspired by xkcd: http://xkcd.com/543/
There are 204 hearts in total.
This version stands about 8.5 cm / 3.4 in tall.
