Free global variables software for mac

Four Variables 1.1 is designed as a free pre-algebra investigation for students in grades five through nine. The program secretly assigns values to four variables (w, x, y, and z) and the student must find these values by requesting the computer to perform operations with the variables.

For example: the student might ask the program to divide x by z; the program would respond "x/z = 0.875." The are two different investigation types: one where all four operations are allowed, and one where only division is allowed.

Global Consciousness Widget pulls from the stream of consciousness in realtime from the Global Consciousness web site. Instead of having pre-determined text, this displays the live text feed from our web site. You can even add your own messages and have them broadcast around the world. Every minute when new messages are pulled, the widget will zoom to the message origin.
To post messages just flip the widget over and log in. Registration with the web site is required for your messages to contain your geolocation. When you enter your message it will be queued. The web site then pulls message(s) from the queue for display each minute. When the queue is empty it will randomly pull a message from the database of currently 16,600 messages. Go to http://www.djbradanderson.com/global/ for registration and the message web view.
This widget contains the most advanced 3D rendering of any widget to date. It takes advantage of cutting edge pixel shading found in only the most advanced games to display the shadows of mountains and terrain and to place an atmosphere around the Earth. For older computers it will render the sun reflection spot.
This highly dynamic widget is sure to entertain and amaze. The messages are out of this world.
Extra: The message database is searchable by word through the web site and through a custom Sherlock Channel: sherlock://homepage.mac.com/javalizard/global/global.xml
