This is a very easy way to get students speaking. Use the Spin the Question power point and have students in pairs/groups ask questions based on the result of the spinner.
Use this with some pictures to make it even more specific. Show a picture and then spin. Students must ask a question about the picture based on that question prompt.

Lots of other ways to use this! Even make your own flash based one by using the spinner generators in our Teacher's Toolbox.
