This is the most beautiful thing.  Not only does this look good and provide light, warmth and cool, but it take bottles out of the garbage.  

I am going to do one of these myself this summer.  I am collecting beer bottles from everyone I know.  When I get close to construction I will know the amount of bottles I am short and may ask for some help from you fine people, but at the present moment, there is no short of beer loving individuals.
