@Marek:
Love the render. As someone above me said, it's definitely one of the best coin renders I've ever seen.
I've already mentioned Titanium and steel textures in the BTT thread, and CfB came in with Palladium.
How much work is it for u to make a couple of examples with those textures?
Heres some other inspirational pics:

and:
Love to see your renders with these...
On the subject of the whole "-coin" thing, the concensus seems to be that we need to position/describe NXT as both a crypto-currency (in it's first form) and an eco-system built on that currency (as NXT evolves into whatever BCNexts plan is...)
So we have been trying to move away from the "Nextcoin" tag. (He says, on a forum called nextcoin.org

)
But, on the other hand, the concept of "-coin" is easier for some people to get. And it is a very cool image.
Ideas mode: maybe u can develop it further as a sort of future-coin. Think coin/computer chip mash-up, or the hexagon idea from the BTT forum. MC Escher coin, industrial chain/sprocket coin
Any one else with ideas/feedback?
