Screenshots & Screencasts

Common sense:

No sane person would ever admit they judge an operating system by its screenshots.

Highlights of the HelenOS 0.11.2 GUI

This screenshot captures some highlights of the 0.11.2 release. We see the new Navigator (file manager), text editor with improved user interface, UI Demo with menu and text being entered, GFX demo printing a name of the current demo screen, calculator with menu.

HelenOS 0.11.1 GUI

HelenOS all-in-one with new GFX-based GUI (display server, libui)

This screenshot captures some of the most prominent HelenOS features, such as a graphical user interface, support for sound, IPv4 and IPv6 networking, multitude of file systems, and a 64-bit multithreaded, multiprocessor kernel. The picture shown by the viewer application is called Colorful Prague and is a courtesy of Miroslav Petrasko. The large yellow building with red roof and about a dozen chimneys touching the left border is the School of Computer Science of the Faculty of Mathematics and Physics, Charles University in Prague. That building could tell stories about the history of HelenOS.
