Here on MacLearning.org we're hoping to begin publishing reviews of mobile apps from the iTunes App Store. I've posted my first (on Doodle for iPhone), but need your help. What apps do you use that others in our community might find valuable in their work-lives in education? What apps have you thought about purchasing but haven't?

I'm all ears!

When I get the urge to create a quick screencast, I usually have a bunch of windows open and 10,000 icons on my desktop. Though I want a nice clean background for my screencast to properly highlight the content I want to capture, I rarely want to make the effort to clean up my work environment. That's where this handy little utility called "Backdrop" comes in. It's so simple that I can describe what it does in a single sentence:

Backdrop covers your desktop and windows with a colored background, effectively cleaning up your workspace without moving a single icon or closing a single window.

Here's a quick screencast (made with Screenflow) that illustrates the app:
