Tagul is an interactive Word (Tag) cloud. Each word is linked to a website so it becomes a navigation tool for the viewer. How it is different from Wordle is
words are interactive, it is a tag cloud
you can have several different fonts
you can have the words in a shape
It can be time consuming as you have to go through every word to delete common words or words that you don't want to appear in the cloud. It is still very new and the developer 'Alex' has stated that there are more features to come. In this example I used my blogsite 'ICT Teaching and Learning' to generate the words for the Word cloud, all the words in the cloud point to Google but this can be tweaked to point to other websites. Once you have played around with it for a while it is quite easy to mix and match colours, fonts, shapes and backgrounds.
It will be interesting to see how this application develops and how we could use it in education.
