American Science & Surplus (http://www.sciplus.com) has a motion sensor w/ different scary sounds & lights that's meant to go inside a jack-o-lantern, for 7.95. I'm sure it could be used in other ways, too. They have some neat stuff at this site, and you can sign up for e-mail notices when something you might be interested in arrives or is on sale, which is how I found out about the sensor. I've ordered several times from them with no problems.
