OK, I finally had a nice day to take photos of the setup, and some of
a perfect round (no, it wasn't posed! 8-)

It is a lot of fun to shoot at the moving targets, but a word of
caution ... darts can rebound off the outside rotating / spinning
balls depending on the angle of attack (trajectory) of the dart. So
be sure to keep the target area clear on both sides, ay least 1/2 the
distance back towards the shooter.
