In the Van Ness Muni Metro station this week, the widescreen, real-time map of the system wasn't working, and the screen was frozen.
The small Application Error box from Adobe Flash Player 9 was explaining that the memory could not be "read," and nobody monitoring the screens had bothered to click "OK" to terminate the program.
Was the Muni system an innocent bystander in the war between Apple Corporation and Adobe over the web animation software, "Flash"? According to Laughing Squid, a brilliant T-shirt called "Poisoned Apple" has appeared with art by a Malaysian illustrator named Lim Heng Swee, which you can buy by clicking here.
