Check out Planets, an interactive solar system visualizer. It lets you change the focal point so you can see the planetary motions as if you were standing on any of the planets. A great way to understand retrograde motion.

Heavy debt has dragged several newspaper companies into bankruptcy. The industry’s dwindling revenues have forced some money-losing papers to close, and papers that are for sale are having trouble finding buyers.

In this animation, catalogued space debris are shown accumulating around Earth in 4-year increments, including payloads, rocket bodies, and fragments. While the debris objects are not shown to scale, the representation of their density is accurate.
If you have Windows, you can see this high-res version with Microsoft HDView, but it doesn't work on a Mac. I was able to see it with Parallels running on my MacBook.

Well, fortune was smiling on me last week, and I got a hold of data for Target opening dates and locations (thnx, Cole). So here it is - a map that shows the growth of Target from 1962 through 2008.Nathan has promised to combine the data from this map with his previous work mapping The Growth of WalMart, into one map where you can see the differences. So we'll keep our eyes out for that.
The advantages to players are that you can see places to avoid (areas with the highest deaths), and the locations from where the most kills come from. The map above shows the total data for the map called The Pit. But you can narrow down the information based on the type of weapon used. For example the map below shows the locations of the kills made with the sniper rifle. Meaning that shooting from these locations have been the most successful. (Also helpful if you keep getting killed by snipers and can't find them)
"Heatmaps are the Doppler Radar System of Death in Halo 3. We're tracking encounters, weapons used and their results in a given game, collecting that data and sharing it with players visually. The key here is 'the darker the red, the more frequent the deaths (or kills, depending on the parameters)'," Bungie explains in its weekly update.
The goal of Burj Dubai is not simply to be the world's highest building. It's to embody the world's highest aspirations. Burj Dubai looks different depending on where you're standing. For those living nearby, it is a shining accomplishment - tangible proof of Dubai's central role in a growing world.Thanks Alwyn!
