By his own account, Martin Frost “paints pictures that people can’t see.” A fore-edge painter, Frost constructs hidden worlds between the pages of books, revealed only to those who know where and how to look for them. The idea that such beautiful images could lay unknown to or undiscovered by a masterpiece’s owner is at once heartbreaking and delightful.

Got an idea? @bobby will draw it (for a fee). Over the past week or so, one of Twitter’s more prominent personalities has put his artistic skills to work for, well, if not good, than at least … money? If you’re looking for an illustration of, say, a “wiener dog in a wedding dress that got left at the altar,” a “stolen Volkswagen 2012 Passat with a bengal cat riding passenger seat,” or even “God’s butt,” then venmo him at his new account, @moneywanter.

“What are you reading?” It’s a simple and intimate question @subwaybookreview asks commuters all over the world. While explaining a book should be a rather straightforward task, the responses are often as revealing of the person as they are the work in question, making for great reads in their own right.
