I think we're still in the "concept" phase...nothing written in stone just yet.
To summarize the ideas so far as they were advanced (in no particular order):
1. A hi tech theme utilizing concepts from older skins like "Copperdeck", "Giger", "Capsula" and "Thredz"...but not the actual graphics.
2. A seasonal theme.
3. A high tech/scifi dark theme.
4. A space exploration/Mars theme.
5. An "Ancient meets high tech" theme.
6. A "WC 2014" theme.
Perhaps an idea unifying a number of suggestions:
7. A high tech/futuristic theme unifying the past and (possible) future of skinning...not utilizing graphics from the older classics but the ideas/spirit behind them? I'd love to see a mock up of what's planned for WC 2014 (maybe just the colors) so that a Theme could be generated using those colors in its elements.
I like the idea of unifying the past and future a lot because of the 20th Anniversary of SD.
