U2 and particle tracks

U2’s new tour makes use of a very impressive shape-changing video screen designed by Chuck Hoberman. What piqued my interest was the images in this video of the screen in action: I’m pretty sure that they’re using photographs of particle tracks from a bubble chamber.


If you click on the image to enlarge it I’m pretty sure that you can see a neutral lambda baryon decaying into a negative pion and a proton on both the left and right of the screen.
