Spell with Flickr

This isn't rocket science, but it is an easy way to spice up your PowerPoint. Many people add keywords (tags) to items on Flickr (a web 2.0 photo-sharing sight). Erik Kastner uses those tags to index photos of letters. His site lets you quickly piece together words from said photos and even copy the code for use online. It'll make more sense if you go look.
