The meeting together of the identical oblique views causes a “fractal-like” background effect down the center- very cool. (Version 1: The images on this pad have been kept darker in order to emphasize the hands and allow the background fractal design to remain more subtle.) Great mousepad for radiographers, radiography students, radiologists, orthopedic specialists, ortho surgeons, physical therapists, radiography instructors, etc. See the lighter adjusted version below: Blue Hands X-ray mousepad (version 2) by BeckCalliView more custom mousepads on zazzle.com
