Two very creative guys at the MIT media lab have created Fuzzmail, an "emotionally expressive alternative to email." On the site, for free!, you can compose a message to anyone with an email address. The Fuzzmail software records your typing - its speed, its starts and stops, the errors, go-backs, erasures, embellishments - and sends your pal a link, so he can watch the email unfold all over again, exactly as you created it. Confused? See some examples here. Now go, you know, get fuzzy.
