<p>Most people like to receive cards on special days like their birthday. The subject of a recent Kickstarter project</a>, however, may be about to change all that. Prankster Travis conjured up the idea of a musical birthday card that never stops playing a cheery tune. When the lucky recipient has enough of the jingle and goes to press the music control button, they get a sneaky surprise. Rather than switch off, the good wishes get louder!
