I have introduced SketchUP to the students during their lab time.  SketchUp is 3D design program that can be used to build structures, architectural plans, or just about whatever you want.  The kids really enjoy it and if you would like to download it you may do so here.   Kids, always make sure you ask for permission before downloading anything.
