Ooooh... very nice. I will teach operating systems next semester. Can I use your icons on the titlepage of my note? Of course I will make a note about this page.
These are all quite lovely. I especially like the KDE and Debian icons. It'd be cool if you had the Gnome icon in different colors and monochrome Ubuntu icons to correspond with the newest releases. Then again, I can do that myself in a few seconds in GIMP. so I'm good, haha.
Great job on these (two years ago XD).
You can modifiy my Gnome icon for personal use..
There's no problem if you don't publish or spread it on Internet
