Karsten Schmidt (aka toxi) is a London based computational designer merging code, design, art & craft skills. Originally from Germany and starting in the deep end of the early 8-bit demo scene, for the past 2 decades he's been adopting a trans-disciplinary way of working and been laterally involved in a wide range of digital disciplines. With his studio PostSpectacular, he is actively exploring current possibilities at the intersection of design, art, software development and education and applying these in a variety of fields.

A strong conceptual thinker and always striving for maximum creative freedom, Karsten’s design approach is based on treating ideas as software at the heart, which in turn informs all other facets of each project. When not creating, he travels the world consulting and teaching workshops about the generative design approach, open source and employing code as creative tool.

He's been an early contributor to the Processing.org project and to various books about programming and graphic design, and his work has been featured in the press and exhibited internationally, including the MoMA, New York and Victoria and Albert Museum, London.
