Further to the link posted on behalf of OA on Facebook, I would like to offer an idea; one that is an extension of a idea quite often mentioned.
Some have said that we ought to be looking for the signature of Dyson swarms, which would be a large object emitting roughly the same power level as (say) a Sunlike star but all in deep infrared.
My extension of this (maybe it's been said somewhere else, but I haven't seen it) is that we really are thinking too small. For example, AFAIK nobody has worked out the reason for the existence of spiral arms in many galaxies. Maybe they are a common type of engineering project?
