The portraits you make on IR-7000 are not merely for spicing up your address book. They are integrated with a "game" and that game is called Brain Drain.
In Brain Drain you choose a portrait to play as, and face off against a different portrait using psychic abilities. It is a bit thin on gameplay and soundtrack but it is kind of fun.
Eons ago I wanted to see if the outcomes of the game were pre-determined based on the character features or if there is some RNG. So I cloned one character to see. It turns out, there is some RNG.
The mid-late 90s personal organizer. The big companies making them were Sharp and Casio, although there were a lot of other ones.
I still have mine, the IR-7000, made by Sega. Looks like this:
Still works turns out.
Like the standard organizer it flipped open and had a QWERTY keyboard. It could store notes, addresses, do calculator functions, time zone calculations, set an alarm and show you a calendar. Plus, a hilarious "human portrait" maker along with a simple game you can play with the portraits.
If two people had IR-7000, you could use its infra-red communication to exchange messages, but I never came across someone who also had this organizer. The industry was really fragmented toward lots of different organizers and everyone seemed to have a different one.
The modern equivalent today would be something between a cellphone or tablet. Cellphone and tablet subsume all of the functionality that these organizers had, but in much more general-purpose ways with fuller software stacks. I can understand why these fuller software stacks are desirable yet in my heart I'm always keeping a space for the long battery life and reliability of this specialized tool for specific things.
