Any idea for a community icon and banner?

I see that we're still lacking on that front on this community, which is unfortunate. Do we have any ideas what we want for this, to spice up this sumo community a bit?

For a banner, I thought we could always change it around accordingly to what yokozuna we have (for example, now a picture of Hoshoryu and Onosato edited in together), or the current winner of the basho.

For an icon I'm not sure, something stylized and more permanent, but what I don't know yet.
