Hi to all, i like the logo3a (maybe inside the center cube something simple draw could give a complexity effect, like the current but a little more complex) and logo3 (they seems more "stable/static"), but also logo2 can works for me (it's more "dynamic") ... but to give a sense of "opening", have you tried move the cubes to the left part, and open them to the upper right side, and move the text to the lower right ?
For colors I'd use standard default Terra colors, or why not also some standard Apache colors, taken for example from the Apache logo ... like their red. Ah, important, try also to see how it is rendered also in small formats (without text), like for icons ... circles etc in some cases are rendered bad in small resolutions. Sandro
