I've been thinking hard about this, and I have to agree with you both, sitters and Blywulf. The idea I had isn't working, at least not for this icon, and I've been overcomplicating the icon design. Thanks for all the time you spent on it, sitters, and I'm sorry for making the job so difficult. I'll be getting a machine of my own again next week so I can start playing around with models and textures again to save you some frustration.
The glowing crossed Kerrblades are a nice idea, but I think they may be too hard to make out at the scales we're using for the geoscape. If I didn't know they were Kerrblades, I'm not sure I'd be able to make out what they were at all.
Let's simplify the design and get some ideas together. My new proposal is to reduce the image to a single white (not sure whether to keep the glow or just make it a silhouette) Kerrblade on a black background.

Winter
