3 Animated dolphins. Tested on Oculus Go (with touchpad) and VR BOX2 (with joystick).
For tests on a desktop (Windows 10 + Chrome) the "inline" webxr session and
A,S,D,W,↑,↓ keys for navigation are used.

One dolphin from the old "3 Dolphins" low polygons model is morphed
(see comments at one dolphin demo).
