Here's a couple of images I made with fractint2.62 and AmigaXv2.05.
I guess it's purely accidental that I ported both..

Title..eh..um..call'em math-devil since the image(s) does
kind of look like a devil's head of some sort..
(add some imagination if needed..:-)

You can view them with xanim..
(ok, any other amiga iff viewer will do..)

frac2.iff - the inital image.
frac2edge.iff - edge detection algorithm in Xv used.
frac2emboss.iff - edge detection and emboss used.

Fractint and AmigaXv can be found elsewhere on aminet.
