Feuerstein not only paints, experiments, works away in the lab, builds and crafts, he also writes peculiar utopias. One would be tempted to call them a sort of bio-punk, at all times in keeping with the latest developments in media and technology, and asking questions on (...) the subsistence of humans, and of the natural objects and beings, in today‘s highly technical environments. (...) So Feuerstein‘s work is characterised by boundary crossings and experiments, yet he doesn‘t want to dominate or even torture nature, rather making it an ally in his work process. He keeps crossing the genre boundaries between literature, laboratory and art. And from the multiple combinations of nearly all forms of art and discourse emerges Feuerstein‘s very own aesthetics.*
