Don't think Sinkhold is a bookcase because of its shape and contents. Owing to its stainless steel construction from a series of sinks, it holds many things an ordinary bookcase cannot. As such, it is useful in a number of post-bookcase scenarios: terrorist attack, GMO crop blight, even zombie apocalypse.
Just toss those books, pull the shelves and invert the sinks over up to three infants, cats or purse-dogs: instant individual bunkers! Or use it to carry your produce to the farmer's market in the parking garage after the widespread failure of Monsanto's platypus-corn causes mass starvation! And when everyone's burned their wooden bookcases to cook food or scare off zombies, you'll still have this to shove against the windows when the hungry hordes come a-knocking!
The shelves are held in place with only spring tension, so they can be slid up or down when empty and brace more firmly against the sides when loaded. Welded from parts of a fun-park carousel, restaurant sinks and a roll-down gate, this post-industrial, post-consumer furniture is easy to lift, even fully loaded, and as such is perfect for itinerant students or that literary bedouin in your life.
