Have you heard of this?

It’s really kind of cool. There are prompts like: take it in the shower with you, drop it from a significant height, have someone else write in it for you, pretend you’re doodling on the back of an envelope while you’re on the phone, etc.
I bought it months ago and put it aside. I’m looking forward to doing it to completion now.
What do you think? Would you want to do something like this?
