G'day PilotinControl,

If you're interested in icons that are a little fancier that solid squares, check out "Perl/Tk Transparent Icons".

The page itself is rather old; it was last updated in 2007. I only found it a month or two ago when I was trying to create a hexagonal icon. The Perl code, as far as I remember, was all valid and I didn't need to change or fix anything. Some of the Gimp instructions were a little dated; however, it was easy enough to adjust the 2007 instructions for my 2019 Gimp version.

I've never used any modules in the Win32:: namespace — I can't offer any help with that part of your question.
