Yesterday at Bundeskunsthalle in Bonn: A lot of people showing off weird symbols at the audience of Marina Abramovic "Lecture". Pic related. Looks like a bull head in an upside down triangle. Satanist symbol or coincidence? Also many butterflies on shirts. Spirals, moons, stars, pentagons (not pentagrams) all the stuff you would expect.
Abramovic is now in FRANKFURT btw. maybe some anons can talk to her again. and make a video of it.
