I've posted this here before, but here is a link to their web page for all 
who are interested. This is one of the few concepts I think has a real 
chance at succeeding...

He who thro' vast immensity can pierce,
See worlds on worlds compose one universe,
Observe how system into system runs,
What other planets circle other suns,
What varied being peoples every star,
May tell why Heav'n has made us as we are.
