Educators have been looking for a way to screen-capture iPad
tutorials ever since Airplay technology was announced. Until now,
people have been using complicated set-ups that might include mirrors,
televisions, capture cards, converters and more.
With the release of Reflection (http://www.reflectionapp.com/), none of these convoluted solutions are necessary – assuming you have a computer running OSX 10.6, an iPad2 or an iPhone 4S.
For $15, you can now mirror your iPad onto a computer. This means you
can use the full power of desktop screen-capture software to record,
narrate, and annotate your iPad tutorials or simulations!
