=======================================
 Visualizing the motion energy filters
=======================================

This example demonstrates how to display a motion energy filter from the pyramid.

    pyramid = moten.pyramids.MotionEnergyPyramid(stimulus_vhsize=(768, 1024),

The animation should look something like this:
