I understand the concept of making an opaque when I read it, but can't quite grasp how to relate it to what's going on with the overhead. Before I tear it apart, wanted your opinion. Thank you!

I love that lense! Paperweight sure, it wouldn't be a bad weapon either! I also purchased a front surface mirror from http://www.sciplus.com, not sure if it'll work for me yet , but it was cheap! When I'm done, I'll post the results somewhere and let ya'll know... and yes I am from the south.

This was a great tool. I worked in an Oakland scrren printing shop years ago, and used an opaque projector for various layout projects.
