- The Optical Illusions blog has written about a new optical illusion created by Daniella Bresanelli and Manfredo Massironi of the Universities of Padua and Verona.

- If you’re looking for something fun to do with your kids that is educational at the same time, and you want to use some of your decks that are still good for something, try this Valentine’s Day game. The catch is that your kid has to read the rules and teach you.
- As others have noted, the Documentary Channel will air its much-anticipated “Women in Boxes” on Feb. 9. The show features in-depth looks into the lives of the women behind some of the greatest magicians in the art.
