The MegaPenny Project starts with a single (US) penny, and steps up to a pile of a quadrillion (via blackbeltjones.com). In its own way, almost as boggling as the Powers of Ten page I mentioned a while back (Thursday, May 10, 2001).

I guess it wouldn't be too good an idea to spend much time looking at the MegaPenny Project before bucketing for a Beltane Fire Society Busk...
