I would like to see the flash player appear more seamlessly integrated into the site. Could you turn off the border around it, and give it the same background as the rest of the site (instead of the black/gray gradient it currently has)?
If no one else likes it, you can always put it back. I know how much people like to dig holes just to fill them back up again...
That way it would appear more like the maps are just floating on the page, and not a part of something else.
Another site does that and it bugs me. I prefer the border.
Make it an(other!) option maybe? I've just been testing this and it does look rather cool with Electric Monk's Biohazard map...
My Infection map is most of my motivation. I think it looks quite a bit better over the stripes than over the smooth background. And something seems odd about the way SimCity looks with the border crowed in right up next to the edge of the board.
