There are a lot of things you can do with your free time, or as TI refers to it, "brief stints between jails". For a result of making less-felonious use of that time, check Engrained Works
Started by a photography buff/former Seattle City Planner to pass the time after she got laid off, EW turns vintage books into hand-crafted pinhole cameras, each of which capture unique full color images on 35mm film using the same principles as a camera obscura, in which light passing through a small hole in an enclosed space is reproduced upside-down but with its perspective preserved, at least until it leaves Catholic school. Some highlights
The Pirate: This red hardbacked number with polished wood guitar knobs started life as a classic tale from a collection of stories called The Waverly Novels published in the early 1900s by the guy who brought you Rob Roy -- you must moisturize, Liam Neeson
Claudia: Upcycled from a book based on a collection of stories the author first published in Good Housekeeping and Redbook in the '40s, this worn blue joint boasts black knobs and a shutter made of gray leather, which wouldn't have that problem if it had only listened to Liam Neeson.
Zane Grey: Boasting all black fittings and remnants of the book's original black/gray cover art, this faded red shooter's constructed with what's left of a tale from the prolific Western scribe who's known for idealizing the Old West, despite the fact that stats-wise, Tom Chambers owned him.
So you don't suck at photography, every cam comes with advice on approximate exposure times, sample photos, and a set of instructions, or as they're known in jail, T.I.ps.
