If you like to text when you drive, then you might just end up on a TWIT (Texting While In Traffic) billboard. Passengers and pedestrians have been snapping photos of people texting for twitspotting.com, a website designed to let texting drivers know that they are being watched, and judged.

The TWIT project was created by San francisco graphic designer Brian Singer. According to Singer’s unofficial estimation, “For every nose picker, there’s 20 texters”. And so, the website was born, and the images started flooding in. Some of the photos have been posted on billboards throughout the San Francisco area.
