The 2D file browser for IRIX was pretty nice, with vector icons. https://sgi.neocities.org/1.png shows an example from https://sgi.neocities.org/ .
I made a mistake when I said we used it for demos. We did not use fsv for that. I was thinking of buttonfly - see example to the left of http://www.sgistuff.net/software/irixintro/images/irix-4.0.1... .
I did try out fsv, but again, it was slow on the desktop machine I had, and not useful.
