You may have seen my post on the new Pentax K-x DSLR a couple weeks ago. At the time I had come across the Japanese site for the camera, but could not locate it at the time of writing the post. All that has been cleared up now. By going to the following site, you can see and customize the camera in a vast assortment of color configurations. Unfortunately the site is in Japanese, but I am sure you can find an online translator service or poke around until you find the right links to customize your own.
Here is my favorite, chocolate Ti.
