The renowned artist Joost Swarte designed a new stained glass window especially for the Oosterkerk in Hoorn. A short film has been made about the design of the window. The initiators for this are the Oosterkerk, the Westfries Museum and Pop-up museum Expost. A good example of cross-pollination from Cultuur Hoorn (the partnership of all Hoorn cultural organizations). The film lasts about 10 minutes and is shown at all three locations, including Westfries Museum. An overview exhibition of the work of Joost Swarte can also be seen at Expoost.
