sandmill.org is the personal website of Dan Mills, a product leader based in Berlin, Germany. The homepage is a Mac OS 8 desktop emulator running in the browser — visitors can browse the site inside Netscape 4, join a live IRC channel (#sandmill on irc.sandmill.org), and chat with MiniBud, a bot that lives on the Mac.
