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!

It's not "public domain crap", it's just s bunch of books written before 1923 or that the copyright's lapsed on.  The sci-fi is before the age of computers, really.  It's mostly the source material for steampunk on there (Verne, Wells, etc.).
