The 2010 DIFFA Dining by Design event produced some pretty amazing tables. Check em' out.
This has gotta be my favorite. It was done by students at the New York School of Interior Design, and created entirely out of recyclable or repurposed materials.
Cindy Crawford hosted the event, certainly to push her line of home accessories at J C Penny. Her table actually looks quite nice though, if overtly simple.
