Acoustics is such a high dimensional medium yet one humans can readily manipulate... This reminds me of [1] (2016), where they optimize a 3D series of conduits so that they produce the desired output signal (given object shape and output audio frequency).

I wonder if one can arrange such conduits (6-way connected pipes and chambers) to replicate a feed forward neural network. If it can be done with light...

These pipes could be interesting to work with, maybe in order to build DAGs. Plenty of software take DAGs as an executable input! Can someone put me in contact with the people at [dynamicland]?
