Useful little tool that someone posted about on the Polymer_Clay_People yahoo group : http://bighugelabs.com/flickr/colors.php
It allows you to upload a photo and it will generate a coordinating color palette. Great for web design or just jumpstarting clay color choices. I could see it being really useful if you wanted to pick coordinating colors (in clay or beads) for an image transfer. And it would be great for picking kaleidoscope objects for a harmonius image.
