About this 3D model

This is derived from the writings of Paul Liu, in particular: http://hippomath.blogspot.com.au/2011/06/making-your-own-pendulum-wave-machine.html Still a 'work in progress' but can be seen in action here: http://youtu.be/LVjnVPLGuDc I made the 'bobs' like little pill bottles so weight can be added - which I've yet to do though I do have some lead shot on order. I hope that the shot will make the bobs swing more accurately and reduce the tendency to crash into one another. Once I have the weights then I will retime each pendulum again (the centre of gravity will have changed) and do it more precisely which I hope will extend the time that the bobs swing in a coherent manner.
