What? You don't want to buy someone else's design? Do what I did. Find one of your artworks, I this case I chose an illustration I did with ink and oil pastel. Photograph it outside in sunny daylight, hi-res of course, and crop it in Adobe Photoshop according to the size of your laptop. Mosey on over to your local printer with a CMYK pdf version and print it on a semi-gloss paper. Smear on some krazy glue (Elmer's glue will not stick to metal, and your design would peel off a few hours later; been there done that) and call it a day.
You can now advertise for your services and invoke whatever emotions, grand metaphors, or philosophic narratives you like with your laptop cover. Grab your frappa-dappa-mocha-choca-dirty-chai-espresso-latte and organize your desktop or add a blog entry.
