If Google has its way, the days of sharing web links through copying text (or bumping devices) will soon be over. The internet giant has released Google Tone, an "experimental" Chrome extension that shares your browser's current web address to other computers through specially crafted sound bursts. So long as the recipients are within microphone range and use Tone, they don't have to lift a finger -- their machines will pick up the audio cue and start surfing. There are a lot of variables that could sour your experience (don't try this in a noisy room, folks), but this could still be ideal if you just have to send cat videos to everyone within earshot.
