Really? Really: 

[I]t’s all part of an interactive art experience by ReAllocate called Project: Blue Sky.

Before looking up to see a UAV, festival-goers will have previously visited ReAllocate’s ‘dome’ to complete the first part of the art experience. At the dome, visitors can interact with a photo booth fitted with Kinect cameras, where with 3D software, their photos will be turned into 3D models. Instead of waiting for the models, attendees can leave the dome with a GPS transponder, free to enjoy other aspects of the festival.

By the way, in case you’ve ever wondered what my Twitter avatar is (and, oddly, some have), it’s a pair of 3D prints of my head. #oddJobPerks
