Christmas in 2008: At the cult exhibition “Oh Tannenbaum,” there were Christmas trees galore, but no curatorial committee: Whatever was delivered was exhibited, as long as it was a Christmas tree. Oh, how joyful. The cult Christmas exhibition has been around since 2004. Originally started as an internal joke, the student project developed over the years into a national art sensation. For one week (the week before Christmas), anyone could exhibit, whether professor, student, or staff member. In 2013, it was over for the Christmas tree. We think it's a pretty cool thing, and it might be worth thinking about again.
