Nice comment from Dibyendu on twitter this morning set off the following exploration...
Research note: It would be good to have a tool that had more flexible borders and the ability to show the wave patterns when there are speakers at the top, bottom and coming in from the right hand side. More clearly emulates the condition of living in an environment where information is coming from all sides.
Another issue Dibyendu brought up and building on a observation of Sean. If one imagines Figure 1 rotating on the axis of the dotted white line, a whirlpool emerges.
Using Figure 2 as an emergent pattern a different kind of whirlpool forms if rotated around the dotted line, This time in the shape of a bowl. The notion of whirlpool to me is connected with the creation of pull. Not sure where this is going yet, but seems to me Figure 2 might be a visualization for bottom up development.
Figure 2, is the same settings with a closed barrier between the bottom and top. The shape transition from Figure 1 only by inserting a closed barrier. At the moment of observation, there is no new energy coming into the the bottom half of the Figure. Interesting that disconnecting the energy still creates new patterns.
