Oh man, you continue to make the awesomest stuff. In the end my Dynamic Lighting Recorder script turned out to be less useful than I'd hoped - apart from the fact that I got bored fixing all the bugs, I found that I was customising the dynamic lighting paths a lot more than I'd anticipated, which made the script much less useful than anticipated. In particular, cutting doors into walls was something I did a lot, which meant redrawing the recorded paths. I guess a combination of your "handles" approach and a way of linking paths to tiles might be the best of both worlds....
