The ET66 calculator from Braun, designed in 1987, is an icon of modern design. It may look familiar to some as its minimal design influenced the appearance of the first iPhone's calculator app. The Braun ET66 calculator is considered one of the most popular and purest form of Dieter Rams’ design. It is also the pinnacle of the “less is more” philosophy.
