6 luthiers to make guitars from old wine barrels. 
THE SIX LUTHIERS:

• Adriano Sergio -- Ergon Guitars, Portugal
  
• Ulrich Teuffel -- Teuffel Guitars, Germany
  
• Nik Huber -- Nik Huber Guitars, Germany
  
• Andy Manson -- Andy Manson Guitars, Portugal
  
• Claudio & Claudia Pagelli -- Pagelli Gitarrenbau, Switzerland
  
• Michael Spalt -- Spalt Instruments, Austria
  

All famous in their own right.  I had high hopes that you would get some spectacular guitar designs using this wood, but alas they went into a different direction and concentrated on creating art work diverging from guitar form and function.

Here is an example of their past works:

   

And here's the barrel project guitars:

   

Not what I expected. I was hoping for incredible, modern guitar designs which maximize the beauty of the old barrel wood.  These seem like art pieces, and the ones that are more like guitars, tend to look antique and old -- not modern. The guitar from Ergon Guitars seems to be the most modern while still looking playable as a guitar.
