I created a Chicago Blackhawks start button. It cycles through 3 team logos depending on the button's current state (idle, hover, pressed). It is a little big, but still looks pretty good. It looks awesome if you setup double height taskbars (which I have). I can post pictures of my taskbar, if people need it.
I couldn't find any other buttons out there so figured I'd share one I made. Hopefully this will be appreciated and used by other Hawks fans so everyone doesn't have to spend time making their own.
GO HAWKS!!!
