A FUN COPYRIGHT CASE TO LITIGATE

Does the new Olympic logo for the Rio de Janiero games infringe on one used by The Telluride Foundation? There was a story by Chris Chase on Yahoo! Sports yesterday comparing the two logos and also a painting by Matisse that has similarities to both.  If this one ends up in litigation it could be very interesting.

The works involved are below, Olympic logo first, followed by the Telluride logo and then the Matisse painting.  I think we can safely assume Matisse didn't copy from the other two, but what about the Telluride logo?  Is it based on Matisse?  Is the Rio Olympic logo more likely copied from Matisse or Telluride or neither?  What do you think?
