Woodworking Plans Review

I need to make a magic lantern for a communications class project, and i was wondering if anyone had any plans on how to make such an object. An example of what i need to make can be found at http://chestofbooks.com/home-improvement/woodworking/Handicraft-For-Boys/How-to-Make-a-Magic-Lantern.html the only problem with this design is that my project is due friday so i cant get the lenses they are talking about. Anyone have any ideas?
