The logo must work with or without the "Software" part. The idea is to focus on "3Stack" bit, but still read "3Stack Software" so people know what we do.
The designed symbol/logo MUST:
* Be Vector / 2-D Style / Flat / Solid symbol.
* Minimalist design
* Work as a single colour + Monochrome (Black or White)
* Has an "icon" form suitable for an App / Favicon
The designed symbol/logo MUST NOT:
* have heavy usage of effects like box-shadows, gradients etc.
* Be cliche, or tacky (eg. cheesy cloud, poor usage of "3" or "S" letters or 3-d)
* Contain elements that look poor/ degrade when scaled down
