Oh cool there is someone out there 😎
Well you making the right 'interesting' point here. The interesting part lies in the making of. Each light effect was created life and unique from different somewhat famous Light Painters, who participated in a big meetup called Light Up Berlin with people from 20 countries in Berlin taking part.
This Light Painting was the last picture taking during the event. I felt super honored as one of organizer to be surprised by some of the biggest artist.

If you are still curious see the video about the project and want to find out who it was, see below.
