A similar system, I'm sure, but he got the material specifically to match the metal of the MacBook and is gauging if other people are interested in it.
You could just use a clear vinyl and trim it to size before sticker bombing your laptop. Matte or gloss depending on your taste, and stick to the automotive ones for UV-resistance and lasting quality. I’ve been doing this for years on work laptops using a 3M clear vinyl wrap.
I think there's a large overlap between image-conscious Mac users and image-conscious developers, for whom laptops are an expression of self or something like that.
