Random question: Does anyone remember a (translucent?) device (toy?) that was about the size of a graphing calculator and had a little antenna sticking out the side, and you could wirelessly send messages to other people nearby (within a couple hundred feet probably) with the same device? This was probably around 2001.
The Cybiko was a handheld device that ran apps/software installed through the Cybiko desktop program. It has small antenna that allowed Cybikos in proximity to communicate. It had games, productivity apps, and communication software. One of my favorite apps was a speed reading app that flashed one word at a time. I read a couple of books in that format as a kid. I convinced many of my friends to get one in school. Teachers never realized we were playing games and chatting in school.
Yes, I still have two Cybikos in my desk drawer. Dead batteries but I'm sure it wouldn't be hard to get them working. I bought one for myself and one for my soon-to-be wife back in university in early 2002. We had a couple classes together and the ability to chat wirelessly was awesome. It wasn't nearly as cool as the Danger gizmo but you didn't pay monthly for it either. I had a ton of homebrew apps for it and some of them were actually really good. Nobody knew what the thing was and most professors thought it was a calculator with a stylus (which was really the antenna).
Edit: I remember using it at graduation, too. My wife was in the audience and I was so engrossed in our Cybiko chat that I took a wrong turn on the stage and ended up getting into the procession line twice. That was embarrassing. Glad I didn't try to use the thing while driving :-)
Yes. I cannot remember what it was called but I definitely remember this. Was it blue translucent? I want to say it was made by Casio but my googling is turning up blank.
