I created a little iconset from KDE1 icon sources for use with 16color Atari displays. It is mainly aimed for the Atari Falcon 030. The set should work with the TOS desktop and Teradesk. Export to other desktops is probably possible too.
I plan to make the monochrome images better, at this time most of them are ugly as hell. Afterwards the icons on plain STs can be replaced aswell.

If Teradesk still shows the monochrome icons under TOS, copy CICONS.RSC over ICONS.RSC.
