It is so simple but yet beautiful. It taps into the desire of
parents to keep everything their precious one does but without the
clutter. Parents take their kids art and send it in to artimusart and they post the images online so the parent can create a book with all the artwork.

"Parents, you’ve got enough to
do. Let us take the worry and the hassle out of preserving your
children’s precious artwork. Sketches, paintings, doodles and drawings.
Beautifully published, shared on the web, preserved for a lifetime."
