A pack of radar-style icons for the wireless connection in knetwork manager.
Just copy the icons in:
/usr/share/apps/knetworkmanager/icons/crystalsvg/22x22/actions

Make a backup first if you want to restore original icons!

You can find in this package alse the original gimp .xcf files.

Was inspired to do this by another icons set for knetworkmanager:
Simple wireless icon for knetworkmanager (from krakatoa)
