Comment 19 for bug 500503

I will stick with my liking of the graduation cap, because IMHO the board will look like a green rectangle, once put as a small icon. You won't be able to see the E=mc2 white letters.
Don't get me wrong, I like the black board image, but I just think that it would not render well as a tiny icon. The graduation cap, with it's more particular form, is IMHO a better candidate for an icon.
