Interesting that this pops up on HN. It was a real nice spot and I'm sad that it goes away. They had really nice holiday activities for kids, but also for adults and elderly. E.g. I myself tried VR the second time in one of the rooms from ZCOM.
I especially enjoyed ZCOM when at one point the Fabmobil visited them and I learned a couple of nice people. Not only computer hacking people but also craftsmans etc too.
Also a couple of times the ZCOM gave us space for our computer club (PPP, rip) in the hope we can benefit from each other. But unfortunately the interests stick to a few great "hardcore" people only, although we offered great and free pizza ;)
Fun times. Not even too long ago...
