monströös created a teaser and various print products for the Leibniz Association to promote the game Twiddle - the museum riddle. With the app, visitors can discover the eight Leibniz research museums. Twiddle invites teenagers and young adults to explore the museums in a new way in an interactive discovery tour. On site, they have to solve tasks related to existing objects. The game is played on site at each of the eight Leibniz research museums.
