This project is interesting in its own right, and links to a cool tool by the same author http://blog.jgc.org/2012/01/international-object-sizing-tool.html http://blog.jgc.org/2012/01/international-object-sizing-tool... for showing the size of photographs, which I just told my Facebook friends about and printed out for my children, who are practicing photography.
