Some time ago we powered a unique album cover project for music artist Melissa Eldridge that involved generated a mosaic CD cover crowdsourced by Melissa's biggest fans. The project involved collecting, moderating and processing the photos, hosting a poster microsite (that allowed fans to find themselves on the cover) and generated the camera-ready artwork for the project.
The CD and mosaic project was featured widely in the press because of the unique way Melissa Eldridge (M.E.) created a cover for her M.E. album that was created by pictures of HER fans. Below is a video clip from Good Morning America.
Here is a large version of the mosaic that can also be viewed at: http://www.tweematic.com/melissa
