iShowU allows you to capture and record anything you can see on your screen, along with audio from any compatible source. They say a picture is worth a thousand words.
Ever been in the situation where you wanted to show someone what was going on, but couldn't? Either the person is not right next to you, not around, in another country... Now just record what you're doing and what you want to say, and stick it in an email!
