Sounds like X-Flight at Geuga Park (formerly Six Flags)
Incredible coaster; definitely on my top 5 coasters list.
A 4-Dimension coaster is not
exactly like a Flying coaster. (those are the names of the coaster-types, btw)
A Flying coaster has seats that, while they rotate in the station, the riders only change position when the track changes from suspended-type (overhead) to regular type (underfoot(?)). You are either on your back or on your stomach, and the track's twists and turns then provide the different viewpoints and whatnot.
A 4-Dimension coaster has a sub-rail iirc, and the position of this sub-rail provides action on a mechanism on the train itself, which drives the rotation of all the seats. They don't rotate freely, but they also don't rotate in a predictable sense, you could be facing an entirely different direction when compared to the train's maneuvers around the track.
It's quite an interesting coaster type, one that brought Arrow (the manufacturer) quite the headache in the following years after it was first introduced at Magic Mountain.
I'd love to go on that coaster, but there are many miles between Ohio and California.
And being an hour away from Cedar Point isn't exactly bothersome.
