How can I make an endless zoom with endless objects appearing and an endless environment?

Hey guys

How can I make an endless zoom with endless objects appearing and an endless environment appearing, too? Like a "Fractal Zoom".

Can someone help me? I am very new here in Unity and feeling so lost with my idea :(

Are there any Tutorials or someone, which can bring light in the dark of my head ^_^ So I can build this step by step?

Sorry for my bad english.

Greetings Jan Jan
