Thanks MsRR, I'll look into that.

mtm, that occurred to me but I didn't consider it for long because I figured at least half a dozen other builders would do the same. It is simple and even implied as a good idea in the challenge description. The only way to win with something like that is to create it in a unique way or mostly perfect way, which I believe
trekdude already has (love the spider, by the way, although I wished it was able to move around a bit more). No, I wanted to do something different... which I still haven't decided on. I either want to do something iconic to Halloween, or something scary. It would be great if it included physics...
