Rams, speaking in German, delivered a speech about the challenges facing contemporary designers in a consumer society, including materialism, disposability, and visual pollution. He followed this with a more relaxed Q&A session, in which he discussed some of his classic Braun designs - the TP1 portable turntable, the T1000 world-band radio, the TG60 reel-to-reel recorder, the ET66 calculator, the T2 lighter, and the MPZ2 juicer - in relation to his famous 'zehn thesen zum design' ('ten principles of design', first published in 1995).
