Bluetooth repeaters are set up at intervals in the park. At the start of the show, everybody tunes in to see a stunning masterpiece of virtual pyrotechnical wizardry on their iPhones and the like.

but none the less one bun for environmentally friendly-- not_morrison_rm, Sep 10 2012 Actually, if the system could be programmed to cause iPhones to explode, you could convert that fishbone to a bun -- 8th of 7, Sep 10 2012 Hmm, terrible echo in here..

That might make a more realistic fireworks effect!-- pocmloc, Sep 10 2012 YOU MAKE PHONE KABOOM ME GIVE BUN-- ytk, Sep 10 2012 random, halfbakery
