This is a really neat idea. "Wall to Wall Carpeting's album (Piliad Echons) artwork is based on the title of the band. It has lead the designers at Bend to experiment with basic insulating materials such as cork.
Home-made cork board made with collected corks and old frame and used some nice big wine glasses to have corks spilling out of them, love it! It's art and a functional cork board at the same time :) Would be a fun idea for a seating chart.
