I just found out about TypoEffects on the Educational Technology and Mobile Learning website and since it seemed fun and useful, I gave it a try.

TypoEffects is still in beta and free for the time being, at least. It converts your images into typographical images or word clouds. There are two types of generators -  the Row-Text Image Generator allows you to insert an unlimited (?) number of words, while with the Word Cloud Generator you can use up to 16 words  only.. What I like most about this tool is that it lets me choose which parts of the photo I want to leave without the text. Also, it's possible to zoom in/out and there are a lot of colours to choose from.
