His name is "Boulet." Just Boulet. He's French. He's had a blog for years and what we have here, as you will no doubt notice, is a rough French-to-English translation, but the words don't matter that much. This is a fantastic voyage, one of the coolest I've seen on the Web.
What happens is a vaguely bored bearded guy with nothing much to do, one day falls (or dives?) into his toilet bowl and goes down a sewer pipe, then into a cave of some sort, out into a cloud-filled sky, then into a field of mushrooms inhabited by Nazis, who get eaten by dinosaurs, who then chase the guy into a pond, or is it an ocean? It's not like anything I've ever seen, he keeps falling and falling and you can go at your own pace using your cursor. Even if mushrooming your way through the universe isn't your thing, try this.
One of the coolest parts — and this has always fascinated me — is that wherever he goes, no matter how remote, how distant from anything familiar, graffiti artists have been there before him and have left tags. That's true in real life.
One time I was kayaking in the Hudson River and for the fun of it, I slipped under some mostly broken down wharves. And on the underside of the piers, only three feet above the water level, were endless graffiti, paintings, images, painted (I don't know how because they were so detailed) in rich profusion where no one would ever look or go.
Who knows why?
Who knows why this guy goes where he goes or sees what he sees, but it's the weekend — if you're in the mood, why don't you go too?
