I do not think there are cursors for Sputnik. If you have CursorXP than maybe you can make your own. It would seem easy to do. Just ckick the configure button in the mouse properties window (from the control panel from your computer) and double click on the cursor you want to change. I do not know what color is the transparancy but I will guess it is white or maybe pink.
So, get some image from Sputnik or create your own and save it as a png file or a bmp file.
