QtEntity is an implementation of a component entity system. Features:

• Components can be efficiently stored in linear memory.
• Component properties can be shown in a Qt property browser.
• Editor is configurable to show specific editors, for example a color picker for editing a color property.
• Properties can be lists of things.
• Not tied to a specific render engine or game engine.
• Examples for binding to OSG and QtQuick
• JavaScript bindings through Qt

Pretty interesting! I will have a look into this.

I've done one entity system myself using C++11 features (like variadic templates) and QObject as base classes to enable signaling. It's really not optimized. Maybe I upload it in this forums too :P
