I'd be happy to help. Take a look at the materials on the site and see if there is anything in particular you'd like to know. The first step is to see if there is a local plastics shop around to make the actual plexi part. Generally there is something around for the hobby crowd and the sign making business. If not, I can help dig up some internet custom shops.
Other than that it is just a question of whether you have one or more small point and shoot cameras. I've been documenting my experiences with various cameras here:

What Operating System are you running? We've mostly finished the port to Windows and are testing how easily the software moves to OS X, but it would be useful to know what people are using.
