Concerning supercomputing and an ET demo: in the past we used a neutron star simulation on a Raspberry pi cluster and instant jpeg slices for visualization. It was slow, but worked. With the new pis we could try either the same, or a very low resolution binary neutron star simulation (but that might still be too much, even with the new pis), just for demonstration. Would there be interest? The code still worked on the pis last time I tried, earlier this year. 

I would volunteer in trying some parameter files, but would need a connection to the (full) new cluster.
