I came across this app while looking through my twitter feed and @smeech had recommend it. I have been telling teachers and schools for a while not to spend a lot of money on Elmo's or Lady Bugs (See iPad vs Lady Bug and Elmo) as the iPad can do similar things for similar money. With the Stage: Interactive Whiteboard and Document Camera app you now have the ability to use the iPad camera with some of the functions an Elmo or Lady Bug has. For instance a teacher can project in realtime students work, class materials, outlines, etc. There are also some added visuals to enhance the presentation such as; adding labels, using a laser pointer or drawing/writing to emphasize certain aspects or content. This app has a lot to offer the only thing I wish it had would be a save capability so video and annotations could be saved for later viewing and reading.
