Donate a word for Unicef
It’s just a demo of a concept but it’s impressive.
Using the spell-check-window of Google Chrome as a medium, the project reminds people of children in need of education whenever they misspell a word.
Every time you misspelled a word, the contextual menu will remind you of children who don’t know how to read and write. You can donate that misspelled word to the UNICEF program and thus contribute to the good cause. The donation is dependent on the number of characters in that word.
