David Jones wrote a rather nice patch based on one by Kamel Biskri. Simply,
it  removes  the  borders drawn round icons by Workbench, in WB2 and above.
This  is  how  the  old Workbench 1.3 used to do it, and it also looks very
nice nowadays with Magic Workbench icons.

However, David's patch is rather yucky. For a start, it's HUGE (676 bytes).
Also,  you  have  to  run  it sometime after Workbench starts but before it
starts  drawing icons, otherwise 'a few' borders are left drawn in, and you
have  to  choose  'Redraw All' from the Workbench menu. Furthermore, if you
quit  Workbench  and  restart  it,  the patch stops working - but you can't
re-install it.

So,  anyway,  the correct solution is to throw the program away and use the
excellent  NewIcons  instead,  which does this job and more. But, for those
who don't use NewIcons much, I've written an equivalent patch - OldIcons.

Installation:
Put "OldIcons" in your S:user-startup any time before Workbench starts. The
patch  is  permanently  installed  until  you  reboot,  even if you restart
Workbench. You do not need to run it more than once, and you do not need to
'RUN' the command.

Requires 2.0 or better.
