Me neither @vasil-danev! This is pretty cool indeed. I once tried this with my teacher waaay back. I remember waving some lightstick really quickly and trying to stay hidden behind what I wrote (my name). That project felt really mysterious at that time and to be honest this still feels and I would like to learn this technique!
thank you!
