You could, but you don't have to
This morning I met with three people, including Eric, who brought his budding portfolio. He asked me how to show websites and I made a haha about how you don't have to put it in a computer screen with a keyboard, because with the navigational clues we can figure out it's a website.
Then, an hour or so later I was trolling for blog ideas and revisited my tribute-to-own-trip-to-England theme and started searching for UK design. The first firm I found was Toast ("we won't burn your bread") and I was checking out their work and found the above image.
I think it looks good.
