Thanks guys! Really appreciate it.
Yes, you guys are too smart.....its a stone henge replica (and in fact has the easter island heads right next to it). It is located in West Texas.
I used After Effects for all the compositing visual effects, took awhile though......alot of tracking and masking involved but I wanted to create something immersive. This was a test to see what was possible with aerial video and compositing. I have more work coming so be on the look out.
