Drupal is a content management platform that allows an individual or community of users to easily publish, manage, and organize a wide variety of content on a website. In general, Drupal is used for community web portals, discussion sites, corporate web sites, intranet applications, aficionado sites, e-commerce applications, personal web sites or blogs, resource directories, and social networking sites.

Well, this is an interesting application. Subliminal message flashes a text or image message for a split second at a set interval of time.

“You may be surprised that you can perceive a very brief and dim flash of a text message or picture. Because of its perceived power and influence at the subliminal level, this effect is not allowed in TV advertisements in many countries.”

(If you need a good message to flash, feel free to use the one I used in the screenshot.)

OSXplanet shows lives images of the earth and other planets on your Desktop. You can see where in the world it’s day or night, pick from over 1000 cities to view, and choose from several map projections. It can also visualize clouds, storms, volcanos, and earthquakes. After you’ve had all the fun you can have on earth, switch to Mars, Venus, or the moon. Very cool app developed by a 17 year old.

Credit is also due to Xplanet, on which OSXplanet is built.

Smell-O-Mints is a pretty little periodic table of the elements, and is a simple but well-organized app. A pulldown menu lets you easily view the table according to state, radioactivity, metal vs. nonmetal nature, etc. There is also a search feature to find elements and a link to Wikipedia to learn more about them. Click on any element to view more information, including weight, radioactive properties, and atomic number. Science is fun.

Introducing the first app in our new “scientific” category: Quantum GIS. Quantum GIS is an open source GIS (Geographic Information System) application that runs on Mac, Windows, and Linux. It’s sort of a professional grade version of Google Earth, allowing you to work with detailed maps in raster, vector, or database format. It also opens files in the format produced by Arc GIS, the very expensive GIS app for which Quantum is a free alternative. This will be a great app for people in the sciences or education who want to do geographic studies without all the expense.
