Twitter Word Cloud Bot
A Twitter bot that can build a word cloud image from the tweets of a Twitter user. The images are uploaded on Imgur.
You can see it in action here. If you want a word cloud for you Twitter account, tweet "@wordnuvola #wordcloud". If you want a word cloud for another Twitter accout, tweet "@wordnuvola #wordcloud @<other-twitter-account>". You should get an answer in the next few minutes if the bot is online, otherwise you'll get it when the bot is turned on again.

The languages supported are English, French, German, Italian and Spanish (thanks to https://code.google.com/p/stop-words/). For the other languages, stop words are not filtered so you probably are going to get the most common words in that language.
