Fermat's Last Theorem
A couple of days ago, my mathematically inclined son Ben sent me a link to the above google logo and the accompanying informative background material from the Christian Science Monitor
I'm always curious to see what the logo designers have in store for us (and sometimes just a little disappointed if they fail to celebrate a day of significance on my calendar such as Shakespeare's Birthday or Lughnasa). The concepts are endlessly creative, and never fail to contribute to our collective cultural literacy. I love that!
