Today's Gratitude Item: Managing to screen-cast my iPad. Whilst there are a large number of apps which allow 'in-app' recording, recording one's iPad / iPhone is strongly discouraged by Apple for security reasons. This makes sense right up until one needs to show 7th graders how to access the isometric grid (and turn off automatic point labelling) in the iPad app version of Geogebra (which is different enough from the PC version to make screen-casting the iPad a really good idea).
