There are other attempts, but either they are limited in scope or ease of use: 1. This Exquisite Forest - https://chrome.google.com/webstore/detail/this-exquisite-for...

2. There was (is?) a Motorola Montage project that was available as a Chrome extension "Ninja". It seems to have disappeared. Here is a Git link: https://github.com/motorola-mobility/montage

3. Adobe Edge animate is there but it is a toy as of now.
