Always looking to cut costs and save $!!! Here are a few programs I have come across recently:

Celestia

“The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.”

GRASS GIS

“Commonly referred to as GRASS, this is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies.”

Mars MOLA Viewer

“The Mars Orbiter Laser Alitimeter experiment carried on the Mars Global Surveyor spacecraft produced a topographic map of the entire surface of Mars. The data for this map is available on the Internet. The Mars MOLA Viewer will download this data for you and render it as a 3-D landscape which you can “fly” through in real-time.”

GIMP (I have shared this before, but it’s so good I’ll share it again!!!)

“GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages.”

This final item is Shareware ($), but from what I can gather and comparing it to similar specialized software it seems quite reasonable.  The demo should give one a good trial run to see what it can do.

SAILS Speech Assessment and Interactive Learning System

“SAILS promotes learning by focusing the child’s attention on those aspects of speech sounds that are the basis for distinguishing the various speech sound categories.”
