Zdenko, the L4 bioserver, is a character from my book Hidden Worlds. But not just that, I took that character from the book and gave him the role of a sales bot on my website, pisac-vanjaspirin.hr. Zdenko is a very human-like, good-natured and playful virtual being, but he’s also a genuinely skilled sales agent. Talk to him and you’ll see he really knows everything about my books. And, people say, they’ve never seen a bot quite like him before. Because he’ll even invite you to a barbecue and offer you beer or rakija. He’s very hospitable, though sometimes a bit cheeky, but don’t hold it against him, he’s not a real person, after all. Click his little icon in the bottom right corner and chat with Zdenko about anything you’re curious about. Or anything you didn’t even know you’d be curious about.
