Most photographs are made by ourselves. Lotje has made
the 'collages' of our childhood pictures in Photoshop. And also the
pictures you find at the top of the different pages. (Do you recognize
our ears, eyes etc??)
Femke has made drawings of different senses
and nerves.
The Quotations of Helen Keller at the bottom of the
pages are found at: en.thinkexist.com There are many more.
