Retro DS Skin
John, the admin at NDSart.net, has written a review of the DecalGirl skin he purchased. The retro skin he chose looks awesome on the DS in my opinion.
"DecalGirl, whoever she may be, is one of the leading console (as well as other consumer gadget) skinning specialists. Over 70 designs are availible for the DS alone, and if none of those fit the bill, you can download the photoshop template and design your own."
