Here's a novel idea: being able to easily send something besides text and pretty pictures in email. iVideoMail and iVoiceMail are Mail plugins that take the legwork out of recording video and audio clips for easy emailing. They install as preference panes within Mail, and once you customize a message's toolbar to add a button for either plugin (there doesn't seem to be any other way to use them when composing a message), you're ready to start emailing your beautiful mug and American Idol-worthy voice to anyone who can handle it. Just don't blame us if your friends and colleagues begin removing you from their address books.
I only briefly tried out the iVideoMail demo and it works pretty well, although the resulting 6-second 320 x 240 video in MPEG4 was 376 KB, which might be considered a little large by some. By why not judge for yourself? Demos are available via a rather annoying submit-your-email-for-a-customized-download-link process, and a license for either plugin is a mere $10 USD.
