On Friday evening we started the 4th hackathon in the project #VR4Rehab. This time we were guest at the St Mauritius TherapieKlinik in Meerbusch. Kristina Müller organized a very well visited hackathon with 7 challenges and a lot of professional participation. Unfortunately I had to leave after my presentation, but my colleague Koen took the honors. Next time in Bruges in October.
