Nice, thanks, addToPic: does seem to do the trick and save a bit on memory to boot.
Some of the backgrounds objects I'd like to add I initially defined as actors so that they could have cycling animations occurring. I see that I can pull the same trick with Act new: and addToPic, but it doesn't seem that using setMotion in that call
((Act new:) view: 532 loop: 2 cel: 0 posn: 83 85 setPri: 1 addToPic: setMotion: Fwd)
works to provide movement. I'm taking a look at the Animate kernel call, not sure if that could be helpful? I haven't done any direct work with cast or gCast, though, and haven't figured out yet how it works, if it's even the right thing to look into. Would this be the right direction to experiment in, or am I going about it all wrong? I feel like it's probably possible, although it could just be wishful thinking.
