Geo Greeting is a neat little tool that allows you to create a message that contains up to 40 characters. It uses satellite images of buildings from all over the world that look like letters. The link it creates can be posted on your blog or emailed. It doesn’t generate an html code for embedding, but you can create a screen recording like the one below (AC/DC background music not included). This would be a fun way for students to practice spelling words. All the links can be submitted using a Google Form. It would also be a great way for primary students to chant word wall words.
