More specifically, in Firefox on Android it shows some kind of multi-colored star with no descriptions.

That's correct. When you click the rays of the star, descriptions of the different Gnod sections should appear though.

I did. I must admit though that clicking 8 or something rays without having a single clue where they'll take me got old really really fast IMO.

I'm no UX-er but I think this is what is described as mystery meat navigation.

Clicked the center a couple of times, tried scrolling and went for the comments to see what this was about. Cba going back.

I see. It is basically a collection of discovery tools using machine learning and experimental visualizations. The front page is an experiment on its own. Meant to be somewhat self referential. You have to discover what it offers by playing with it.

This is called mystery meat navigation and it's always, always a terrible idea.
