ColorwarePC offers a distinct way to create a personalized iPod. They'll color it for you. For $74, they'll tint your iPod from their palette of 28 colors. Pick one color for the click wheel, one for the front housing, one for the back. Some of their colors are flat. Others have embedded metallic flakes that shimmer under bright lights.
Don't have an iPod? They'll sell you a nano or a video model with custom coloring from their in-house stock of new iPods.
Unfortunately, it's already too late to order one of these by Christmas. If you placed an order today, it would arrive early-to-mid January, meaning that you'd have to stick an IOU into someone's stocking.
The coloring service, where you supply the iPod, is US-only. However, new purchases can be made from around the world. Contact the company to see whether they ship to your area.
