Cool your home just like the ancient Romans used to do! I've seen The Invisible Library before, but I never did link to it. It's fairly interesting, a sort of academic backwater of the sort that I enjoy examining on occasion. Here are some real books, a huge collection of rare books that was recently making waves in the book community, apparently. I don't know much about it myself, but it looks neat. :)
Looks like I missed out on whatever this was. The vice fund - making money the old-fashioned way, through taking advantage of the weaknesses of others. If it wasn't for the defense contractors, I'd probably invest in them myself.
