Now that we have Google’s automatic captioning on videos on YouTube, which I like very much, what about speech balloons around the captions? It’d be more helpful if the location of the voice source could be indicated by an arrow from the balloon and the voice tone could be expressed with different balloon shapes.

If your gestures could bring motion characters that can be manipulated on both sides, video chatting would become like a fun video game.

When your girlfriend throws a kiss when video-chatting, many hearts appear moving towards the thrown direction. You can touch and move the characters on your side.

Wink and get stars. (Can characters go beyond the chat window like this?)
You might think of lots of other gestures and fun characters.
