headphone lighthouse

So there you are on the train/tube/waiting room listening to your ipod at 3/4 max volume, safe in the knowlege that you are a) irreparably damaging your hearing and b) really winding up everyone within mosquito tst-tst-tst range who isnt equally sonically protected (or just deaf). Life couldnt be sweeter, or could it? How about if you could also really aggravate people out of earshot? How about that guy at the end of the train carriage reading hs newspaper, if only you could annoy him too. Well now you can, apply the headphone-lighthouse to your headphones and turn that wasted sonic energy leaking out of your headphone into an even more far reaching beam of light. The sound can seed a chaotic pattern based on a dripping tap, guaranteed to catch the peripheral vision of everyone within line-of-sight. Even that guy reading the newspaper wont be able to ignore your feeble-minded self-centeredness now. This simple device can massivley boost your typical Sphere of Annoyance (TM) from a respectable 268m3 to an ego-rattling 14,137m3.
