Array duplicates look identical

When I add the array modifier here, the duplicates in the video look different - in my case they look exactly the same. What did I do wrong? 

In a different video I've used a noise texture and the array modifier and they were different. A bit confused right now.

    Solved it: I forgot to move the Array modifier to the top! neat.

    Glad you solved it! The order of the modifiers makes a big difference indeed.
