The Internet is riddled with pornography: arty porn, glamorous porn, gruesome porn and perhaps most of all baffling porn. If you can imagine it, it exists. If you can't imagine it, it still probably exists

Erotic Falconry Sure, it's just a photoshop prank (arty-looking soft porn pictures with precariously-perched birds of prey), but as the founder of the now-dead site says: "Maybe we can get the raptor-love movement to really take flight"

Green Porno: Eco-friendly porn does exist - one site raised $120,000 for rainforest preservation last year - but Green Porno is a series of short films made by Isabella Rosellini. She appears dressed as different insects, making insect love. It would take a special someone to be aroused by Ms Rosselini in a stripy bodystocking, deelyboppers and giant wasps' eyes.

Slug Porn: Can you really find people turned on by slugs? Internet community Metafilter tried to find out. After a few BBC Wildlife links, they found a small but enthusiastic underworld of slug fetishists, posting crudely-drawn cartoons of multi-breasted slugs reclining by log fires. And until you've seen a one-legged snail girl dressed as a Manga cheerleader, you haven't really lived.
