We invited to the third edition of the Places _ VR Festival from 16 to 18 September 2021. Once again, we attracted XR enthusiasts from near and far to Gelsenkirchen-Ückendorf and, after a year full of social distancing, wanted to offer the XR community even more platforms and opportunities for exchange. Together with the team from lala.ruhr, the project “imagine green urban futures” focused on sustainable urban development in VR & AR.
