Stickers have become normal when we chat online. It could express more emotions than texts. However, I found there’s a detail could be improved to make stickers more expressive—change direction of a stickers.

 If stickers towards the right direction, chat would be more interesting like this.
 Now I am exploring to achieve this by deep learing in JS. I will report my progress later.
