This screenshot shows Haiku OS (image build from 28th May 2006) running in Qemu under GNOME on GNU/Linux (Arch).
Haiku OS window shows a bash terminal and Tracker (file manager in Haiku and BeOS) window called "Haiku".
Edit: Note also that I have changed the background color as well as added those two indicators (belonging to the ProcessController program) in the top right besides the clock.
