UVB-76
Intersecting volumes from projected shapes in two axis. Volume is fillled with particles (spheres of multiple sizes). The expression “There are two sides to every coin”, made me want to explore that concept – but with iconography and lettershapes. 1080 x 1080px at 60 fps.
Excerpts from the Wikipedia-article about UBB-76:
UVB-76 (Russian: УВБ-76; see other callsigns), also known by the nickname "The Buzzer", is a shortwave radio station that broadcasts on the frequency of 4625 kHz. It broadcasts a short, monotonous buzz tone (help·info), repeating at a rate of approximately 25 tones per minute, 24 hours per day. Sometimes, the buzzer signal is interrupted and a voice transmission in Russian takes place. The start date of broadcasting is disputed. However, it was allegedly reported to have started broadcasting in the late 1970s, possibly 1976.The purpose of the station has not been confirmed by government or broadcast officials. However, Rimantas Pleikys, a former Minister of Communications and Informatics of the Republic of Lithuania, has written that the purpose of the voice messages is to confirm that operators at receiving stations are alert. Other explanations are that the broadcast is constantly being listened to by military commissariats.
There is speculation published in the Russian Journal of Earth Sciences which describes an observatory measuring changes in the ionosphere by broadcasting a signal at 4625 kHz, the same as the Buzzer.
The most likely purpose is that the voice messages are some sort of Russian/Soviet military communications. The station being a numbers station for intelligence agencies such as the FSB or the former KGB of the Soviet Union is extremely unlikely as messages occur at seemingly random, unpredictable times, while numbers stations use a fixed schedule which changes rarely. In addition to that, the non-changing frequency of 4625 kHz and the low transmitter power are unsuitable for reliable communication from Russia to Europe, where spies would be stationed.
