Here's a small favor. Please gather for me a dozen or so of those tablets PCs that have been pushed past their hilariously short half-lives by shinier models during the holidays just ended. Using your mad DIY skills, clamp them to my wall, lined up vertically. Then using your even madder hacker skills, turn the whole installation into a dedicated EarthNow! Landsat Image Viewer, a sort of earth TV from the US Geological Survey that displays, in real-time, images being gathered by the Landsat 5 and 7 satellites when they pass over the United States. So instead of simply visiting the website, I have a digital mural broadcasting the data for me live, scrolling strips of earth like a stock ticker tape. It switches on when the satellites are about to pass over, and goes dark after the last continental slice. Ideally, both times should be marked with a delightful chime.
If you've got time, how about attaching a 3D printer that will spit out an endless conveyor belt of topography?
