Martin Molin and Wintergatan's “Marble Machine” was honoured with a Honorary Mention at the Prix Ars Electronica 2016, category Interactive Art.
Shortly after visiting the fantastic Spielklook Museum in Utrecht with its programmable mechanical instruments, I discovered the Youtube Channel of Matthias Wandel, who has written a computer program to produce wooden gear templates.
