Crazy rapidly-prototyped mystery rings

These rings, which look like their made of rapid-prototyping plastic or cornstarch, have a 64 character message embedded in them, giving you instant geek cred with all your friends and neighbors. It’s not a real product but it’s definitely a cool application of rapid prototyping – essentially creating custom jewelry on the fly. Wouldn’t it be fun if there were rapid prototyping trucks that came through the neighborhood and you brought out a design or an object for them to copy a la tinkers of olden times? Tuppence at model, loves! Tuppence a model!
