Pedestrians are not as plentiful in Los Angeles as cars, alas. So most likely if you saw this, it was on the intertubes and not at a crosswalk.
Total Crisis Panic Button has been installed (at crosswalks) all over Los Angeles by Jason Eppink, a New York-based mutimedia artist. He’s even included a Google map to assist in locating them.
And if you hate those huge video billboards as much as I do, his treatment in 2007 of the smaller street-level version might compel you to take similar action, thanks to this how-to video.
Eppink’s other projects can been seen at his site, Senseless Venn Diagrams.
