I would be honored to have any of my posts in your Maths magazine.

Thanks for your advice. I agree that the first part was a little slow.

The first part of the video, up until about 1:40, I played with only the frequencies and phases of the terms in the heart equation which had some surprising effects. Then at about 1:40 I slowly added in an additional frequency term giving it some amazing resonances.

I like to imagine how molecules are much more choosey about which resonances they will allow their electron clouds jump to.
