# How to animate surface fluctuations

I have experimented with Blender before making some simple low poly landscapes.

I found this example online:

The scene I am trying to animate is very similar to the example above but a low poly mountain range. How can I achieve this effect?

One more thing: Here's another way to do it with the Empty coordinates using a driver, so you don't even need to keyframe. If you type #frame into an input field then the value will move with the frame. Then you can change it to frame/20, frame/30, etc. for finer increments (slower change). This method uses Python, so you can "Reload Trusted" or enable "Auto Run Python Scripts" in Preferences.
