There was a discussion here a while back about "Ahad's constant". This has some cool universe views at near-light speeds:

Also discussed over on usenet. Happy light-speed sailing by starlight!

Good find.

Here is another relativistic flight description. It talks about abrerration of light, and lorentz contraction, and describes that circle in your link as the Janus' circle. When you are travelling at of near the speed of light, you can actually see behind you, without looking behind you. There is an mpeg of the flight thru stonehenge at the end of the slides, but take the time to read thru what is happening....... Pity no one will evere be able to travel at light speed.

Aberation is a weird concept. Stuff that is 90 degrees to you as you pass it, will appear as if it is ahead of you. If you orbited the sun at light speed, it would look as tho you are traveling toward it. :wacko:
