At Virus Books(mostly German, but it doesn't matter), you can download short visual summaries of books for your PalmOS portable. Even if you don't have a handheld, there are images of the results, so you can have a look, anyway.
StorTroopers suck. Long live Scholz & Volkmer's 60/90/60! The whole site is in German, unfortunately, but it's not that hard to figure out. If you want to skip directly to creating your own figure, click "Selbermachen." Otherwise, click "Loben" to view and vote on other people's. Too bad you can't download and post these to your site...
