So let's say you're at a live-music event, and the show reaches that moment -- ironic or not -- when raising a lit cigarette lighter would be called for. But you don't have a lighter because you don't smoke; and besides, the arena is a no-smoking facility. What to do?

Presenting the iLightr application, a virtual cigarette lighter for a smoke-free world. It's just 99 inflation-ravaged cents for your iPod or iPhone.
