An update of the Njam ones, as announced earlier. No more grey beards when the background is darker. All are based on the original, single 32x32 icon. Goals remained a slightly better looking 40x40 icon, and folder icons to reduce the number of default folder icons in use by one. Not pixel-perfect, but an improvement.
I've looked at using PNG, but didn't end up using it. As usual I've used ICONEDIT.EXE to create the folder icons, by using it's sticky selection of pixels (select the pixels you want to replace, switch to the donor image in the list, and select again to select exactly the same, right donor pixels without having to record or remember coordinates and/or sizes).
Again no request, but perhaps e.g. the file WIN1.JPG in a directory of Njam can be used for a 3-D PNG icon. That'll require the removal of text, so there may be better or easier alternatives. All other original Njam artwork is mainly 32x32'ish-sized only, including a 32x32 *.ICNS icon file.
