gradually turning to face a moving object
pretty cool. What does a larger arrow look like? Also, it seems that at less damped arrow settings (lower quotient like 10 or less), the arrow spins/oscillates a bit towards the top when the stars x-coordinate is close to the arrows position (i.e., near the left-hand side).
Almost as if the computation hits some sort of singularity and flips the arrow into la-la land...
For fun, you could extend the example to use a feed-forward predictor algorithm in order to "lead" the star and anticipate its location .
Scott, quite nice. It made me start brainstorming about possible offshoots that use the technique.
I'm also very glad to see that you created this while stationed in Antarctica :)
