I made this wireframe mockup booklet (or call it whatever you want), using 2 picture frames that I attached with two hinges on the side so it opens and closes like a book. Replaced the picture with a device printout and there you go, all you need is a dry erase marker for unlimited mockups!
You can check out some more pictures I attached.
I'll be improving it in the next days (still thinking about a system to keep it closed, and to hide the exterior).
