In the long-range, two communities stand opposite each other - FOPF (general applied) and FAKY (aerospace research).

On one day, the Fopfovs distributed to everyone in each room a printing of nodes and units, placed on each floor on the drummer (the drummers swept the clocks), and at the agreed time the drummers began to beat the drums every three seconds.

In the rooms, respectively, lights were lighted or extinguished.

The building has a running line: "FAKI-M...DAKI"

It happened so long ago that there was no smiley at the end of the line.
