Brummbaer's fine art and underground magazine Germania brought him recognition in Europe during the 1960s, and he orchestrated light shows for musicians such as Frank Zappa and Tangerine Dream. He found his most expressive medium when he discovered the computer.
He was one of the primary computer animators responsible for the special effects in the Tristar motion picture Johnny Mnemonic. He also created an innovative opener for SIGGRAPH’s 1995 "Electronic Theater," and has long been a pioneer in the world of digital animation, where he has been noted for his signature hallucinogenic style.
In the autumn of 2003 he was diagnosed with Head and neck cancer. During several months of chemo- and radiation-therapy he wrote a semi-biographical novel titled RUNAWAY JESUS, which recounted his experiments with the drug dextromethorphan hydrobromide (DXM), followed by What's so Wrong with Love and Peace- Adventures in the European Underground 1965-67. Both available as E-books at Amazon, iTunes, etc. He survived the Head and neck cancer, but in 2007 was diagnosed with bladder cancer, which was treated with two bladder resections. He was cancer free from that time to 2013 when the bladder cancer returned. 2011 RUNAWAY JESUS was published in a German translation as DER GAMMLER. (Werner Piepers „Der Grüne Zweig“)
From 1972–1973 he spent nine month writing and recording “Maschine Nr.9,” a radio play with Wolf Wondratschek and Georg Deuter.Wikipedia
