Play With Clay (on Your Laptop)
Those of you looking for a more hand-crafted look can also create an external cover out of modeling clay. Cover the top of your laptop in plastic wrap, then cover that with a ton of modeling clay that you've knuckled, sculpted, and tweaked into whatever aesthetic you're trying to accomplish.
Next, let the clay harden, take it off of your laptop cover, remove it from the plastic wrap, then paint and drybrush the heck out of it if you really want to add to the beauty of its texture.
Once you're done playing around with your modified clay cover, remove the top of your laptop (just as if you were painting it), separate the electronic bits from the raw case, and set this aside.
Use an epoxy glue to attach the clay cover to your laptop's case, and then clamp these two layers together for at least a day's worth of time to make sure they set correctly.
See why you had to take your laptop apart on this one? That kind of force could do a number on your actual screen.
Once you're done, reassemble your laptop, and bask in your creation--a fully textured laptop case guaranteed to get eyeballs for its unique aesthetic!
