Papercraft Iris Glasses

I really like these functional papercraft iris glasses. I think they would make a good prop as part of a steampunk Halloween costume. Instructions and templates for the glasses may be found at the Instructables website. Iris mechanisms like this have been used in cameras for over a century.
