When enabled, Mail Goggles kicks in at the time you specify (default is between 10 p.m. and 4 a.m. on Friday and Saturday), and throws five math problems up on the screen when you press "send." You have a limited period of time to solve them. If you can answer the questions, presumably you're of mind sound enough to tell off your boss, or pour your heart out to your ex-lover.
If you can solve simple math problems even when under the table, there's an option to ramp up the difficulty of the questions, but sadly they remain in the arithmetic realm and don't drift into interesting algebra or calculus.
To activate Mail Goggles, go into Gmail's settings, and turn on Mail Goggles in the "Labs" tab. Then adjust how and when it works in the "General" tab.
Seriously? I'm hoping this feature shows up on blogging products.
