There are so many clever decals out there, yet I have to say that the Homer Simpson iPhone sticker is perhaps one of the most creative (yet obvious) ones to date. It features a very hungry Homer doing what he does best with the iconic Apple logo.
Designed by Etsy user apjam, the Homer Simpson iPhone sticker can also be used on an iPod touch. I'm sure 'The Simpsons' fans would love to see one developed for their laptops as well. Perhaps we can put in a request.
