I have seen this done in writing workshop at the elementary level. It really is a great way to prompt writing and get the thought process going. I chose to go with the first set of emoji that came up and they actually did pull into a decent story of what was actually going on at the time.
I went to the site, selected the first 5 icons by clicking the buttons. I then put them into a story. Took a screen shot of the completed story and uploaded it to Flickr.
A great daily create creative starter.
