Create a Word Cloud
For your next presentation, here's a simple way to make an interesting graphic of the topics you're going to talk about. Input the text of your talk into Wordle.net and you'll get what's known as a word cloud back in return; the biggest words in the cloud are the ones you mention most. You can then modify the cloud based on text fonts, number of words to include, etc. Here's what a recent speech by Steve Jobs looks like.
You can even input the url from your site to get a tag cloud for it. Here's what Business Hacks looks like.
Even if you decide it's not practical for work, it's still a ton of fun to play around with.
