Creative visuals and ideas for the nervous system?

Me and 3 others are doing a presentation in biology class to teach the nervous system. I need some creative visuals and activities we could do, because that's the only way you can get a good grade. For example, the teacher was very impressed with the group that had to teach the digestive system. They unwinded a roll of ribbon which they measured to be the lengths of the esophagus, stomach,small intestine, and large intestine, color coded, and wrapped it around the class, demonstrating the length of each organ and the whole digestive track. another good idea they had was creating a candyland-like board game except the spaces were going through the digestive system. Does anyone have any creative ideas that could be applied to the nervous system?
