Infomous clouds are interactive. If you click on a word, a drop-down list appears with links to articles that are related to the specific word. The drop-down will also appear if your mouse lingers over a word. By clicking on a link in the list, you will navigate to that specific article. After half a minute of inactivity, the cloud will automatically select words at random as if they had been clicked. By clicking or hovering over the cloud, the normal, interaction mode will resume.
