GoodMorning! is a Twitter visualization tool which shows about 11,000 tweets collected over a 24 hour period between August 20th and 21st. The tweets were harvested to find people saying 'good morning' in English as well as several other languages.

The tweets appear as blocks and are colour-coded. Green tweets are early in the morning, orange tweets are at about 9am, and red tweets are later in the morning. Black tweets are 'out-of-time' messages (sent at times that aren't in the morning at that location).
