Looking for some Math help from the Edublogosphere

I'm looking for some help here. Our High School department has 20 laptops and they don't know what they can do with them. I have ideas, but nothing concrete of how these laptops can "Affect student learning beyond word processing and Internet research." We're talking all levels of high school. From geometry to IB Calculus. I have a meeting with the department on Friday. Can anyone point me to examples of cool things you do with technology in math?
