Wordle is more of a diverting website than one you will visit again and again. It allows you to put in a website url or a list of words (say from a book in the bible) and it creates an image of the words. The more a word appears, the larger it is in the picture. The image above was based on recent posts at free Christian resources so as you can see Christian, God, books, prayer and website were the most popular words.
You can play around with the settings to create different variations. I’m not 100% sure where this could be used, maybe for an outreach leaflet or something?
