We've seen pipes reincarnated into lamps and chandeliers, but Dallas-based designer Stella Bleu presents an intriguing re-use idea: recycling old industrial piping into shelving that allows books to be displayed in a whole new way. And yes, these skinny shelves double as lighting too.
If you don't have a large flat wall, there are other different configurations available -- so if you've got a corner that's in dire need of sprucing up, these pipes might be the ticket.
Of course, Stella Bleu also does the pipe lighting thing -- mixed with shelving. Check out these sconce pipes, which double as both illumination and book rack.
