Ok so I was trying to remember more about this old space/time travel show I saw once or twice when I was very young. I don't remember much, but I was hoping if I wrote what I did remember it might be familiar to somebody. Oh yea, I think it was on public television. All I really remember is that it was a group of travelers who I believed used some kind of ring or yellow egg shaped device to travel around. I remember seeing them all holding on to some ring and spinnng around in space at the end of some episode. It's sad but that's all I can remember and it's driving me crazy... Any ideas?
