BlueEyedOS tried to create a system under [[LGPL]] based on the [[Linux]] kernel and an [[X Window System#Software architecture|X server]] that is compatible with BeOS. Work began under the name BlueOS in 2001 and a demo CD was released in 2003.<ref>{{Cite web |title=BlueEyedOS Demo/Test CD Now Available – OSnews |url=https://www.osnews.com/story/3313/blueeyedos-demotest-cd-now-available/ |access-date=2023-11-24 |website=www.osnews.com}}</ref> The project was discontinued in February 2005.
