## to see or not to see : sheen and shadow

In the blog post “LaTeX and Metafont” two projects which massively scan in books were mentioned. Another mentionable project is the Gutenberg project. Here one can find e.g. the book of

“Hand Shadows to Be Thrown upon the Wall” by Henry Bursill from 1859. Everybody knows this situation: there is a strong video projector light, people sit and wait for some show or talk and someone will start to make hand shadows.
