NCSA TerraServer Blaster - a nice interface to the huge terraserver aerial imagery database.
NCSA Pixel Blaster - a distributed movieplayer for tiled display walls.
vtkPipeline.tcl - tcl/tk script that allows you to browse and modify objects in your vtk pipeline.
vtkFitsReader - VTK class that reads 3D FITS datasets.
pf3dWidgets - I made my own Performer 3D widgets for
