I was looking for some example art that contains the theme 'identity', and I found this website http://www.redbubble.com/ which holds themed challenges to artists worldwide, and their work are ranked by votes.

These are some examples of the 1st place works.

Lost Identity - Imber

(#1 in Le Masquerade and #1 in Broken)

An Incident Involving Four Bottles - AJM Photography

(#1 in Bottles, bottles, CAPS)

What Friends Are For - Kyrstie Kyle Photography
(#1 in Wackily Weird)

Self Portraiture - Limitless - Anthony Young
(#1 in Jump)

And here I just wanted to share a link to an amazing papercut artist: http://www.petercallesen.com
