There is a lot of good entries in your contests that resemble ideas that you posted in design brief, so i tried something different. I made a few variations of design that i submitted trying to cover all of your request from your last post in comments section. There is also versions with only two colors and versions on black background. Unfortunately it is hard to show how small icons will look alike (submissions must follow some rules about size and backgrounds) but general rule is that complicated designs is harder to transfer in icons. I have tried to make balanced and recognizable logo that incorporates idea of building blocks.
