Anyone got any ideas for an icon or banner?

First off, we need a good icon for !newzealand@lemmy.nz. We don't want to change the icon very often, if at all. It needs to work as a small circle and a square.

On the other hand, I would like to change the banner from time to time. I've just put one up, but it's a stock photo. I'd love to use pics from the community. It can be hard to find pics that work because they get cropped very short and wide (740×230 px on the main page, even shorter and wider on Jerboa). Any ideas are welcome, doesn't have to be scenery.

(If you don't know what I'm talking about, go to !politics - the icon is the orange man lemmy, and the banner is the photo of the parliament buildings)
