Knut wrote many articles over the years, most of them in the fields of cinema and video games, but also some on technology or free software. Almost all of his texts were published in German magazines or on German websites. So be prepared to read them in this freaky native tongue of his.
Here are some of the web sources to find some of his work:
Filmpage was a long year project which now holds an archive of his writings on film.
Brave New Gaming is a project Knut started with one of his friends and colleague Thomas Nickel in order to promote small independent download games.
The magazines Knut wrote for include Elektrospieler and the second version of the PC Joker or the download magazine HD World, as well – at the beginning – the internet film magazine Spielfilm.de
