In the Hitchhikers Guide to the Galaxy, Zaphod was put into the Total Perspective Vortex which is the most horrible torture device ever invented.
"When you are put into the Vortex you are given just one momentary glimpse of the entire unimaginable infinity of creation, and somewhere in it a tiny little microscopic dot which says "you are here"
The shear crushing realisation of your own insignificance is supposed to drive you mad (unless you are Zaphod, in which case you discover you are the centre of the Universe)
This website has a similiar goal, to show you the scale of the Universe, its pretty cool. Although I have not gone mad so maybe the universe was made for me...
