I am building a full size R2D2 from scratch, when you are scratch building everything begins look like a potential part, well this lamp I just got from IKEA really reminded me of the little domed one so I got bored and with a little bit of tweaking I got him looking pretty good.
I happen to have access to a cutter, and while it makes it a bit easier it is not necessary to complete this project. You could just get the vinyl and cut it with scissors, or you could even just use regular labels that you painted blue. I would bet that even with sharpie you could get the point accross.
the great thing about R2 is that he has such a an iconic look that you really only have to capture a few bits and pieces to make him look right. The main eye, the stripes and the top sections.
I think from the pictures you can get an idea of panels I had made up. (I might be able to make these available)
Update: sorry folks for the disappearing act, I'm on baby watch and my wife is due any day now so I had to make a mad dash to complete some stuff for work.
I did manage to get these up on ETSY, figured that would be an easy way to make them available.
Let's see these R2 lamps everywhere :D
