Warning: This Advertisement May Cause Seizures

Or at least that's what the video advertisements lining subway tunnels should say. The first time I came across this form of advertising was riding the train in Beijing, China this summer. It was just like any other subway ride in Toronto (or almost, the TTC subway system has always been subpar compared to other major cities) but all of a sudden flashing lights and pictures bombard you from the dark tunnel outside the car. A long line of video screens all displaying the same clips are shown practically like a stop motion. They placed in a way where the speed of the train is calculated and the screens practically look like they're stationary with respect to the train's windows. Except when the train isn't at the right speed they seem like strobe lights.

Goes to show that digital media can truly insert itself absolutely anywhere.

But seriously, I would not go on the subway with these ads if I were epileptic. Instant seizure.
