The room
A desk with the current work on it, a chess board mid-game, a shelf of books, a telescope aimed at the sky beyond the window, and the ordinary things around them: a notebook, a mug, a plant, a lamp, a chair. The room is a place, not a menu: what is in it is listed underneath, and everything it leads to is a link there.
Room
The 3D room needs WebGL. Everything in it is listed below, and every link goes to the same place it would in the scene.
In Chrome this is usually hardware acceleration being switched off: Settings, System, "Use graphics acceleration when available". Safari and Firefox do not need it.
