Perspecta Software was a start-up company founded in 1992 by
[John Ousterhout] and [Larry Rowe]. Its first, and only, product
was ''Perspecta Presents!'', software for Unix workstations to
create and display presentations. (Think [PowerPoint]!)

The product was [Tcl/Tk]-based, even though the [canvas] [widget]
had not been released at the time.  A similar widget to the
canvas, called a ''spot'' widget, was embedded in the executable.

There is some old information about Perspecta Presents!
at http://www.rpi.edu/dept/rcs/packages/ppres/1.10/ containing much of the library Tcl code, some pictures. There are also executables of SPARC and AIX versions.

Several [Tcl'ers] would be interested, for historical reasons, if
the code could be released.
