Backdrop pattern on 3b1

[Forrie Aldrich]

Has anyone discovered a way to alter/change the default backdrop
patter that is produced by (i think) wind?  It would be nice to
be able to change that to something else.

Also, does anyone have a copy of the new windy.c program?  This 
one allowed modification of the mouse icon.  I wonder if there is
a way to run something through /etc/rc or whatever to alter the 
default mouse pattern (ie without having to run windy...)??

Thanks
