XGoldie is an (nsfw) animation of a dancing girl (Goldie Hawn?) for the X11 Window System.
It is based on WGOLDIE.EXE for Windows 3.1 written by Walter Prodorutti.
I have extracted the original bitmaps from WGOLDIE.EXE and converted them to the XBM format.
Prodorutti created WGOLDIE.EXE based on an animation he found on a Mac, however, I'm unable to find any information on this original version.
