Here is a really great little piece of art work called a tube lamp. When I first saw one of these I was really impressed and told Justin Telepak, the owner of IndioArts, he needed to sell these to steam punkers.
The lamps are hand made and have a little of Americana, using nobs from the 1950s/60s/70s. The actual bulbs can be found at local hardware stores such has Home Depot or Lowes.
Justin uses hard wood from South America and each tube lamp is unique and comes in different color variations depending on the wood used.
