The spheres appeared in the second St tng movie First Contact. You could consider them escape pods as it was used when the cube was about to be destroyed. It would be a lot larger than the scaled down model you'll see at Carowinds.
I think The Borg have Cubes and Spheres for there ships if I remember right from seeing ST:Voayger a few times. Not really a Star Trek fan but the Borg are one of the cooler groups of people in Star Trek Universe.
its bouncy. and some of the harnesses arent as tight as i would like. i felt like it would pop loose and i would fall face first to my death. anyways, youre also tilted too far back so the blood rushes to your head when they slam on the brakes at the end of the ride. yesterday was a two and a half hour wait, so i was disappointed that i rode a new coaster that was incredibly bouncy and made me feel like crap. the scape around it is awesome though. if they fixed the three main problems (loose harness, tilted too far back, bumpiness) the ride can be awesome.
