I got this from Hauntiholik. SHe has a great video on her webpage. I purchased the spell book from Michaels and when you lift the lid it says things and makes sounds. I hooked up the motor to an old plug, used a old cog i happend to have and it lifts the book up for me every 45sec or so and it makes it seem like my witch is talking. Hope that helps.
You could make a leering prop. If you have the Halloween-L DVDs from 2005, Mr. Macabre had a guy named king leer that would crouch behind a gravestone and leer back and forth. The head just oscilates back and forth like an oscillating fan.
