The attached image uses data from the "6dF Galaxy Survey"
at http://www.aao.gov.au/local/www/6df/ to visualize our
closest neighbours up to about 2 billion light years ;)

Some noteworthy points:

1. Each dot represents a *galaxy*
2. About 100K galaxies are shown. Parsing takes
    a few minutes, but render is actually very fast.
3. The empty cones are a result of not being able to
    observe through the disk of our own Galaxy
4. The outward thinning is caused by not observing
    fainter galaxies at larger distancees.
5. The colors are not very scientific ;)
