Let's build a beacon to tell aliens who we were.

The most fruitful work takes place on the blog Centauri Dreams, which is affiliated with a foundation that promotes interstellar travel. The charge is led by a pair of twin brothers, physicists James and Gregory Benford (the latter is also a science fiction author), who approach the field of alien-directed beacon-design first from an economic approach. In a paper in the journal Astrobiology, they lay out how one might build such a device without spending the whole GDP.
