It's different from my other sets in that it is entirely illustrator-made (the rest are drawn by hand), and that even the smallest size is not a cropping, but a modified version of the bigger sizes. They are also meant to be used on a dark background to keep all their splendor. Use the included desktop folder, or color your window a rich blue for the best results.
Many thanks to GFXman for converting the OSX icons to XP.
My last piece of advice would be: GET INTO DIVING!
