Here are a set of variations using the traditional iconography for the four armed form of Avalokitesvara. He holds the wish fulfilling jewel or cintamani, a mala or rosary and a lotus. The first picture is a gouache commission painted in 1998
(Go to http://buddhist-pics.com/commissions.php to see more commissioned work).
The other images were created on my iPad using a photograph of the gouache as a starting point. The apps I used were Brushes and Waterlogue. I am really enjoying exploring the possibilities of this touchsreen technology.
