Project Gutenberg

So apparently these hippies have 22,000+ eBooks to give away. Are any of these good? Or are they mostly public domain crap? Anyone trolled through their website and found something worth reading?

They have a torrent of a bunch of Science Fiction books over at gutenberg.org but I haven't found anything cool yet. I'm hoping to snag a book that talks about FLYING CARS IN THE YEAR 2000 WHEN COMPUTERS ARE SMALL ENOUGH TO FIT IN JUST ONE ROOM!

Best bet is probably to use some random torrent site and search for ebooks on it. Can find a giant .rar of thousands of authors with some you might have heard of or want to read.
