Attractions Magazine has put out 2 videos that give us some new looks:
Is that the same scene shown from 3 different angles of the viper wolves? I believe so looking at the similarities in the surroundings (same log and staging of plants in front and to the side of that scene). If so, looks like there may be different versions that may change from ride to ride (one with two adults and one with the babies).
The angle for the one with the babies I think shows a better contrast in regards to how it may really look. The depth created with the layered effect beyond the screen makes the wolves look less like projections.
Are they using the musion/3D hologram technology used with Shanghai Pirates (or think Dumbledore from Forbidden Journey queue or a projected video version of the HM pepper ghost effect)? The entire scene doesn't look to be just a projection on a screen staged behind plants in the front (as I initially thought).
