This option lets you choose the type of board and tiles which are displayed.
If you want to make your own tile sets use the classic tile set as a template
and change the texture and colors for different effects.  When you make a new
tile set that works with Iagno send it to Ian Peters itp@gnu.org
and he will include it with the next distribution.
There are three tile sets which look the same, but have different
animations -- woodtrim, shrink, and blend.
Screenshot of the animation settings.
