Hi,
there're big buttons in attachment.
This is a standart buttons used in Mac OS X but they are were zoomed a little. I think it can be used as icons, so i created topic here.
Hope this will be useful somebody...
I can generate this buttons at almost any resolution. 512x512, 1024x1024 (i have not tested, but i'm sure it will work)... They are drawn by Core Graphics technology.
