This is a simple version of a design I'm still working on, but sometimes simpler is better, so I'm posting this as well. The Escher triangle as the 'A' is representative of complexity and technicality, the driving themes behind the community the logo is for.
I like the icon, but I don't like the font, or the fact that the icon is part of the text.
Try putting the icon above the text like the current logo... and although complexity and technicality are important themes, also consider organic, natural, and progressive themes as well.
