Around 1986 I *had* thought of making such a thing. It would have
been pretty low-tech by modern standards -- standard CMOS logic
shift registers, counters, and an EPROM to hold the data. Running
off a single coin cell would certainly have been impossible, so
the plan was to have a pocket battery pack with an umbilical wire.

As for actually building it, I got as far as buying a big batch
of 256 green LEDs.

Several of the General Technics people have very versatile programmable
LED-badges, but though there are many GT photos on the web, none show
these badges. Instead, lots of photos of rockets, explosions, Tesla
coils, and other photos with intriguing captions like "Setting up for
the magnesium fire. The black bucket probably has sodium in it."

No, not the liquid oxygen barbecue starter guys.....that's an entirely
different group of pyros, apparently. But somehow I bet that the
two groups have members in common.
