Google on paper
This book is on hold for me at the library, really looking forward to taking a peek. I actually find the cover really nice; that ubiquitous blue and green, the simple web-like layout, all topped off with the neutral Helvetica typeface. Designed by Ben Wiseman and Christopher Brand, I found this peek of the cover at The Book Cover Archive.
The envelopes are just a concept from Rahul Mahtani & Yofred Moik from the Industrial Design program at Syracuse University, but I feel like you could certainly turn this into a DIY. Found here.
