Links to Software Downloads:

Netscape 7.2 (http://sillydog.org/narchive/#ns7)
This older version of Netscape has the Composer plug-in that provides an easy way to create web pages without html programming. (Netscape 8.x does not have this feature)

SURFER demo (http://www.goldensoftware.com/demo.shtml)
Full-featured, except for print, save, copy, cut, paste, export ..... but print screen can grab the graphics. This site also includes digitizing, GIS, and graphic software.

Terrain Analysis System (http://www.sed.manchester.ac.uk/geography/research/tas/)
Free with registration. This program provides extensive tools for geomorphology and spatial hydrology. I think it can serve as an excellent alternative to ArcGIS, which costs a bundle and often hard to use.

Waypoint+ (http://www.tapr.org/~kh2z/Waypoint/) lets you download and upload spatial data between your computer and Garmin GPS receiver.
