I've been doodling/drafting a fractual-ly modular bookcase based off a visual pun from more than a year ago as I write this. One day I still want to make that bookcase, but since that initial idea my library has grown too fast (not counting all the boxes I have back home—sorry Mom).
That's where this one came in. It's cheap by furniture standards and is able to consistently grow and change to suit my literary and spatial needs. Also it makes me look rugged.
