I wound up spending my time up on the roof, basically inside the spider.  I could control the legs and have the spider shake, or lurch out at people (though not far, enough to freak people out).

Next year I hope to have more time to build it better.  Actually delivering the candy through one of the pipe legs would work well, having a speaker/megaphone or something would be nice, as I got rather hoarse by the end of the night from “hissing”.

The webs really added to the effect, I had a nice spolight on it, with a red bulb in the ‘mouth’ of the spider.

Several kids, and even a few parent refused to even approach the house.
