The tuning table painted on the wall has become the object of not only informal tourism, but even wedding photo shoots. Eyewitnesses say that not only this wall was painted in a similar style last year.

By the way, this type of table was invented in the USSR in the 70s. Previously, tables printed in a printing house were used to transmit a static picture, which were filmed using special cameras - monoscopes. Today, standard signal generators are usually used for television equipment.
