If you turn on the spedometer-looking display setting, it shows more.
I'm thinking that it's kind of like that Tesseract off of Captain America the movie.
Just now figured out it's throwing a non-existent particle from the last moment destruction.
Oh, and you can distort whe stickmen with this. Looks like a wild ride!
Seems to produce singularity after a while. Gravitational ring enables distortion of vehicle, and heated protons merge with the barrier, which the interaction with singularity, makes it look a little likea warp projection on a z-axis, which is not actually in powder toy. But, nice effects from my point of view. Any one else have a comment?
