the pod is kept REALLY dark.. and my vision isn't all that great, so I didn't notice much of anything. However, I'm going back tomorrow morning, I'll look for you.
As for the barf factor... I didn't puke at all. Riding it 4 times in one hour though... not a good idea. I felt sick for the rest of the night. Which brings me to my first Mission Space tip... RIDE MISSION: SPACE IN MODERATION!
