Celestia is a free and open source space simulator that allows you to explore space right from your computer. Celestia is available for download on Windows, Mac OS X, and even Linux. Celestia has many very cool features, including an eclipse finder.
Not only does the eclipse finder allow you to find solar and lunar eclipses on Earth, but you can seek eclipses on other planets as well. I found out something really cool when checking out eclipses on Jupiter - because Jupiter is very large and has many moons, solar eclipses are very common.
I don't really understand all about this project out of MIT but want to learn more about it. Thi s is what they say on their site:
"ikuli is a visual technology to search and automate graphical user interfaces (GUI) using images (screenshots). The first release of Sikuli contains Sikuli Script, a visual scripting API for Jython, and Sikuli IDE, an integrated development environment for writing visual scripts with screenshots easily. Sikuli Script automates anything you see on the screen without internal API's support. You can programmatically control a web page, a desktop application running on Windows/Linux/Mac OS X, or even an iphone application running in an emulator. "
This incredible website lets you pick all of the software you want and automatically says NO to toolbars and "junk" you don't want on the computer. I'm using it to make sure I have everything on the new computers I'm putting in at school. It is missing a few virtual world programs but overall it saves TONS of time! It even does updates! Works for Linux and PC.
