I know the devs have choosen a logo and design concept for Darkcoin, and I do not wish to steer any controversy about it. However, I have a concept in mind that I would very much like to try out, and would hence like to offer a bounty of 10 Darkcoins, to prominent designers that i've seen in this forum, such as Sigi, Kaene, and others for trying to realize this concept design.
I can transfer the coins immediatelly to a bounty fund or the devs themselves.

I have made a VERY VERY VERY limited illustration of the concept I have in mind here:

The idea is to have some kind of rope/chain inside the letter D.
The rope curls and twists to form the letter K, and by doing so gives a sense of the ropes [coins] merging, shuffling, and separating back, each to its own direction.

I believe a good execution of such concept might strengthen the association of Darksend feature with the coin logo and name.
