Nice presentation. Also a good one for teachers and students.

Condé Nast's Protfolio has a nice interactive page showing some of the new security features for the new version of the US $5 note. The Note for Note link shows how the Euro (€) has additional security features. Other links show the appearances of the US dollar through its history and the "life" of a dollar note.

My doctor told me I was "as sound as a dollar", should I now worry? <g>
