Cycling platforms rather than creating

On the autorunner tutorial, I feel that it would be better to

simply use/hide/reuse a few detailed platforms versus simply creating

random ones. Is there a name/tutorial for what I am asking? If not, could

someone point me in the right direction? I kind of hate the "feel" and

"look" of randomly generated boring blocks and would prefer to spend

more time in illustrator/photoshop making a few nice platforms.

I have this working somewhat in Unity.

Thanks :)

Here is what I want:

Actor

-------------     --------------       ----------------

Platform 1          Platform 2            Platform 3

(on)                  (off screen)        (off screen)

Actor

-------------     --------------       ----------------

Platform 2          Platform 3            Platform 1

(on)                  (off screen)        (off screen)

Actor

-------------     --------------       ----------------

Platform 3          Platform 1            Platform 2
