It would indeed be a fantastic addition - this is almost exactly what I was trying to do as my example netwire project. For a bit more support, I was trying to move a point from x=0 to x=10, and then back to x=0 - and so on. I got as far as getting to x=10, but then had no idea how to reverse the direction and make the whole thing cycle. I was told to read about ArrowLoop, but sadly I never got much further. - ollie
