Thanks for the kind words! This is primarily a taster article to introduce the UAV project, I intend to write a more technical report and publish the designs/code in due time (and some more videos!).

The presentation uses Story Glass, also a project of mine, which we hope to offer soon as a service. It is an experience, lying in a damp field shooting a video to think about how the text will flow over it!
