I once came across a Wikipedia page describing a system where indifferent of the initial starting position, at some final time t=T the system would always reach the same equilibrium position.

Does anyone know what the name of such a system is?

I recall there was an animation of 4 balls each starting at different heights on the same ramp at t=0 and at t=T the balls were always at the same height on the ramp.

Hi Apteronotus!

I think that's an attractor

It would have to be an attractor with some kind of damping, otherwise you would get oscillatory motion around the equilibrium point. You could also call it a potential minimum
