There are several types of dispensers. I probably haven't discovered all the types yet. It might be safe to say I've found the most eager and dedicated. Or greedy, maybe. On the other hand it might not be safe to say anything.
This type sits, is planted, thrives
ensconced (I'm sure you're getting the picture), in DysArc rooms and corridors.
They are big, averaging several times my size and weight. The bordered area
is a screen. Some display something in response to your knob activities while
others show continuous streams of DysArc action, videos, news, and comics.
There are other kinds of dispensers.
