With scenes ranging from landscapes through to cities it makes for a unique view when your have your iPad docked or just sitting around the office/house.
As big fans of timelaspe imagery here on du, the MagicWindow app comes highly recommended. With 10 scenes, the first two are pre-installed with the remaining 8 available for download at around 1Gb per scene. High resolution timelapses take space so the file size is not surprising and they do hold up in terms of quality.
You can download the app from both the US iTunes ($3.99) and UK iTunes store (£2.39). The iPad store is not up and running yet outside of the USA, but if you run a simple search for Magic Window iPad in any of the localized stores it will come up.
