I've tried a couple times over the last few minutes but when I click
on the link that directs you to the actual source code at the ftp
site, it fails (Netscape complains no route to host).

When I saw those requests for a slice viewer, I also started writing
one (since I need one). I've written a complete GUI application using
GTK and vtk (using the GTK widget Prabhu Ramachandran wrote). It
allows you to enter the data set, extents, bits per data, a data mask,
and a data range (which is used to create a linear gray scale map) or
you can enter a file that contains a color mapping.  The interface
could be certainly be made prettier, but it's functional.

A screen shot is available at:

The left mouse button tells you the value under the mouse, the right
button changes the slice and the middle button changes the color
level.

I'd be happy to get it included in VTK if anyone wants. It requires,
Python and libglade since the interface is generated from a XML file
output by Glade. It probably wouldn't take more than an hour to write
the interface code by hand so that libglade wouldn't be necessary.
