I ended up with so many icons that I felt I had to dedicate a standalone page to them, so here it is. Take as many as you like, and please let me know on my guestwall if you know the original creators of any of these. They have been collected over a long period of time from a large variety of places, and I do not know who made them, but I would be happy to give credit. Right now there are over 1500 icons and more to come. There might be repetitions, I sometimes forget that I have already downloaded some... Hover over an icon to get an enlarged view and just click an icon to download it :)
