with Motion for Visually Digesting
Emoji Twitter Activity
I have been playing with different ways to visualize emoji use in tweets, using emojitracker's streaming api (by Matthew Roth) to get the live counts for about 900 emoji.
The visualization is at http://learnforeverlearn.com/emojiviz/. It currently definitely requires a larger screen, and more cpu power than a mobile device is going to have.
