ImageDIG
ImageDIG consists of three integrated modules which allow the user to convert 2D flat images into 3D (x,y,z) data or if a graph, convert the graph in image form into 2 dimensional numerical data. The third module is a full analysis plotting utility where the user can import either the 2D or 3D data saved above or import any number of columns of data from a file. The data can then be analyzed using several statistical functions and plotted.

Teroid Venn Control
Teroid Venn Control is a .NET control implementing the concept of the Venn diagram invented in 1880 by the Cambridge lecturer John Venn FRS. Its purpose is to represent visually the intersection of sets using overlapping circles, and is widely used within many different fields. The control's appearance is set programatically, and additionally the values, item text, title text and sub text can be edited by the user of the client application.
