I told you about vocabulary coulds in previous posts (here and also here), but recently I found out another online tool called Tagxedo to create word clouds with some predetermined shapes. You can create those clouds with the text you type into the box or, as I have done myself, with the text of a particular website. In my case, I have typed my blog address... and Tagxedo gets the more frequent words and transform them into a shaped figure.
These are only four examples:
I hope you like this tool, and I recommend it to you in order to revise for an exam in an original way! You can also use this with your school projects.
