Off topic refresher

I ran across a story about an artist and public school teacher who creates art on his classroom whiteboard during his 25 minute lunch break.  What started as a way to release stress is now used as a demonstration for his students of what you can do in a short period of time.
  Gregory Euclide uses materials from the classroom to create the art, which is eventually erased.

"People who do not see the original have no problem only looking at it on a screen or as a print, but once you see the original it is hard to let it go or believe that it could be destroyed."
