Yes, that secret got me to thinking about my hyperlapse videos (before litchi).
I would send the Spark out to radio loss of signal one direction (1500ft) from me and have it come back.
Saw this video and thought "How about send the Spark out 1500ft to the left of my position, fly through my position and continue 1500ft to my right.
Makes for a very cool hyperlapse with that technique.
