1. Just because a few commercial American events masquerade as raves or fedtivals, doesn't mean all events are like this. You just don't hear about the good events. We have to calculate generator loads because we're running 500-1000 person festivals with permits &c, but it's still an underground party operating by rave rules. No high vis security or police around. Also we're not doing this in the US, please don't project your shitty culture onto the whole world. 2. Aerial circus it's extremely important to inspect the rigging points and the hardware being used due to the sheer amount of force being generated by drops. You absolutely need to know the load of carabiniers, regular rock climbing ones are often not sufficient. 3. Blender could be a fun idea but you often are limited by the room and where the rigging points are, than what you can dream up.
