"Bank of Canada Urges 'Star Trek' Fans to Stop 'Spocking' Their Fivers"

This story is absolutely fantastic. As a tribute to the late, great Leonard Nimoy, an apparently large number of Canadian Trekkies (or Trekkers, as I suppose they would prefer) have been 'Spocking' their five-dollar bills. Take a look at the story for some pictures that show examples of Spocking, which I think are rather well done. I think this is an excellent tribute. I approve!

Bank of Somerville: 10 Pound Denomination

Sometimes, strange things happen in our Somerville mathematics presentations --- like seeing currency from the Bank of Somerville with my picture on the 10-pound note and my colleague Quentin Miller's picture on the 20-pound note. (The reason I am on the smaller denomination is probably because I am a cheap date.)

(Thanks to Andrew MacFarlane for drawing these, and thanks to both him and Tim Camfield for an excellent presentation on paradoxes.)
