…while cleaning my home office, I've found my Java Ring! Wow, it has been a long time since I played with it. Have you seen one? OK, I'll admit it, it's kind of geeky, but it's cool, and is part of Java history… an early attempt on (Java-based) wearable computers. Java rings where introduced around 1998, pre-KVM and J2ME, and are based on the iButton, a computer chip that is enclosed in a secure, small but yet thick stainless steel can.
