The grasp file (.gl) is a archive, containing:

- One .TXT file (read by the grasp command processor).
- Font files (.FNT & .SET), 
- .PIC files (pictures), a header (picture-size/number of colors/palette...),
  followed by blocks of runtime encoded data.
- .CLP files. Like pic files, but without the palette info.

A description of the format was recently posted in alt.sex.pictures.d.
This description is not error free, and should be taken with a grain
of salt (and perhaps some tequila).

If you only want to play a little, you can:

- convert GIF to PIC with the Graphics Workshop System (Hope I got
  this name right). It is shareware and can be found on all major
  archive sites (look for GWS).
- Assemble these into a into .GL files (a .GL composer/decomposer was
  posted to alt.sex.pictures recently). You will need to write your
  own .TXT file though.
- View with a grasprt/grasp1.

If you want to do serious grasp animation, I suggest you buy Paul
Mace's GRASP system.
