How would you create the bubble effect scene in the portal in LIS film

At its more basic, small pieces could be animated. Very brief.

An interesting point I took from a video on youtube while looking for the old clips on tutorials, not much left. The video made an interesting point on the buggy game engine that blender has, the old one obviously, and that a game really works well within a small radius of the origin. So a game with different areas over a distance can become unstable, even though the engine is unstable.

Well, the file I’d like the effect for does work in upbge, interestingly, and luckily. But, the bricks I’m having trouble with getting it working to begin with in the first place. Hmm.
