There is an animation I made back in my early PhD days many years ago that all of us in our group use to try and explain tipping points which hopefully you can see here: https://caboulton.files.wordpress.com/2013/03/double.gif“
I have made a Quicktime screen recording which looks like this:
And through the BellHouse browser it looks like this:
This is a recording of BellHouse playing the looped version of the first recording five times. The settings on BellHouse are: Sampling interval – 1.5, Sampling threshold – 0.1.
This is a really low sampling threshold as I played it a few times at 5, 2 and 1, but got very little response. So I thought i would try it as low as it would go and got this, which I like. The universal chimes at the beginning and the end reflect the colour change from white to black and back again. You can hear the movement across the tipping point and it might be nice to explore this further to see if there is a way to play particular bells or a better range of bells.
I have also realised that it might play differently if I changed the grid size, which it does:
No time today to playtest the other gif but I will prepare the screen grabs etc at home so I can come in later in the week to play it as soon as I get in.
Playing BellHouse .gif 2
Chris has sent through another version of the same data which he has modified after our discussion in the comments of this post. I have made it into a movie so BellHouse can play it and in it you can see several differences.
Here you can see the 2 graphs from the original animation have changed so that the top element is the same data as the left bottom, but a close up in order to see the movement of the “ball” better. The ball has also been filled with a semi opaque red to help it be seen by the motion capture software and the lines have been made slightly thicker for the same reason. As I understand it, Chris’s intention is that BellHouse plays the variability at the tipping point more clearly as this is the element of the data that is most important to communicate.
In playing it through BellHouse there is a noticeable difference in this section of the animation and how it is played, so I think we are getting towards that point. There are some issues with the software to help to make BellHouse read the whole of the image with all its bells, but we are working on that at the moment.
In the meantime this is how it sounds:
I think you can definitely hear the movement of the “red ball” as the curve begins to flatten out and the consquent change in tone as the ball goes from one dip in the curve to the other.
