MetaTree Component (for Delphi 5,6,7) 1.4
"MetaTree was designed for Delphi developers who want to bring a completely new look and feel to their applications.
MetaTree is a Delphi control that allows hierarchical information to be viewed as a graph tree displayed on an elliptical parabolic surface, which allows the user to view all the selected information at once rather than drilling down through folders. The user can modify the display by expanding and collapsing nodes, adding and deleting child nodes and changing the display color of each node.
The user can drag the display to center on a desired node and can select the desired node using the mouse.
The component distribution includes a sample application, MTDemo.exe, both as a compiled executable and with sources. It shows the basic usage of MetaTree component."
