Inspiration: KOZO plumbing fixture lamps

Very cool re-use of plumbing fixtures by the Tel Aviv design team DEMO/Design Clinic. Their stated goal is to reduce their manufacturing to zero, as "everything that you need must have already been made for you, built in another product." These are a good start. The lamps are for sale at their Etsy shop, and reasonably priced between $170 and $230. Note the clever use of the taps as the on/off switches.
Just one question: If something breaks, do you call a plumber or an electrician?
