Gnome designer shares prototype replacement for activities

Activities at least said something but it wasn't clear what an activity is in general.

I don't think this icon really conveys what it does or what to expect from it when you look at it.

Since I'm only seeing people lauding it, what makes this such a great change, because I'm not getting it.

It's great, but it looks weird and is not friendly towards people that have no idea what it is.
