Königsstädtisches Theater was the name of different theater buildings in Berlin in the 19th and 20th century. The first Königsstädtisches Theater was built by Carl Theodor Ottmer in Königsstadt, a former settlement neighboring Berlin that is today part of the boroughs of Mitte, Prenzlauer Berg and Friedrichshain, and opened in 1824. Its first director was Karl Friedrich Cerf, who managed it until his death in 1845. An Aktiengesellschaft from its inception, the theater had to rely on financial support by the King of Prussia. When the monarchy stopped its support in 1840, the theater fell on hard times. Involvement in the German revolutions of 1848–49 meant that the theater was closed in 1851 by royal decree.Cerf's son, Rudolf Cerf, had inherited the license and the name from his father, and named the building used by Circus Renz "Königsstädtisches Theater" from 1852 to 1854. The license then was sold to Franz Wallner, a popular actor, who used the name for his own Wallner-Theater until 1858. In the following years, a number of different theaters used the name but none achieved any lasting success. The original theater building was used for various purposes after its closure. It was demolished in 1932.

Project Blinkenlights was a light installation in the Haus des Lehrers building at the Alexanderplatz in Berlin that transformed the building front into a giant low-resolution monochrome computer screen. The installation was created by the German Chaos Computer Club (CCC) and went online on 11 September 2001 as a celebration of the club's 20th birthday. Some novel uses of the screen are for people to call a number and play Pong via mobile phone or display animations sent in by the public. Similar installations were created by the CCC for the Bibliothèque nationale de France in Paris in 2002 (called Arcade) and for two towers of the City Hall in Toronto (called Stereoscope). Both installations feature higher resolutions and eight shades of grey. In August 2023 a new Installation was shown on the CCCamp in Mildenberg. It was called Polychrome and used RGBw LED which have been calibrated as Tim Pritlove shown in a Talk about the Project on Aug. 16. The electrical engineering and computer science students of the Budapest University of Technology and Economics turn their Schönherz Dormitory into a giant display ("the Matrix") at their annual Schönherz Cup competition, where amongst others, teams compete to create the most interesting and funny animations. A similar display, featuring three colours, is annually created by students of Wrocław University of Technology and the University of Bordeaux,who have released open-source software to create interactive architectural displays. Independently, an installation displaying the message "FERTiG" (German for "FINISHED") was shown at the completion of the Elbphilharmonie in Hamburg in 2016. The term "blinkenlights" originates in hacker humor. One of the CCC installations is depicted in the Golden Boy and Miss Kittin video for their song "Rippin Kittin".
