Vuurwerk letter proeftuin by Lara de Greef

Vuurwerk, or Fireworks, is a collaborative project by the Dutch design group, LetterProeftuin (Jaron Korvinus, Timon van der Hijden, and Yorit Kluitman) and designer Lara de Greef. Based on the printing house tradition of producing a free calendars to celebrate a new year and showcase new printing techniques, the group decided to create a single print that would somehow change throughout the year. Because it could reflect the temperature changes of the seasons, thermal ink seemed like a logical fit.
