Eyejot ("Video Mail in a Blink")

The Eyejot website describes the tool as "video email in a blink." You can use it to make a video of yourself from your computer and then email that video to people. All you need is a computer with internet access, a webcam and the email address(es) of the person(s) you want to send the video email to. The best part is it's absolutely free.

I doubt Eyejot was designed with education in mind, but it can certainly have academic applications:

• The teacher could send an email to his/her students introducing him/herself before the class even begins so that the students will come in a little more curious and maybe relaxed about meeting their new teacher. This is called a "premail." 
• The teacher could also send the students video reminders or announcements about the class. 
• The teacher could teach the students how to use the tool, and the students could send the teacher a video for practice and feedback (and a grade?) in oral language use.

Can you think of another academic use for Eyejot in the language classroom?
