I'm a big fan of Zefrank. For years, he has been creating some seriously interesting web shit at zefrank.com
The Letter Project is one of those super cool creations. Essentially, it's a dynamic alphabet where each letter is made up of someone holding the first letter of their name. To see it in action, you are asked to type a phrase and then watch as the phrase dynamically appears from all the images received by Zefrank.
Please see it and rate it here on 12/21. After 12/21, find it in the Cool Site of the Day archive.
