There was a great page I stumbled upon some years ago that described just how big 256 bits (2^256) is by using work instead of time.
But I can't find it, because I can barely remember any of the details.
If I remember correctly, it had something to do with moving dirt across the the country, or moving water out of the ocean, or something. Speed wasn't important.
Anyone stumble on this page before? It's an alternate approach to Bruce Schneier's thermodynamics analysis.
I found it. It was discussing 52 factorial, or the number of unique shuffles in a deck of playing cards.
