Alternatively, the [R_is_Ris](https://www.reddit.com/r/deepdream/comments/rkljoc/observer_pytticlip_psychedelic_trip/hpdcdfy/?context=3) vesrion > `[cos(pi/a),cos(pi/(a*b)),d*cos(pi/(a*c)),cos(pi/a)]`, where abcd are constants that suit the motion of the scene (higher value, slower rotation)

this isn't a docs thing, but this feels like the right place to put it for now: https://github.com/moble/quaternion

something like this: ``` python -m pytti.workhorse conf=empty init_image=/home/dmarx/Downloads/joe-biden.jpeg scenes="'[/home/dmarx/Downloads/van-gogh.jpg]'" height=512 width=410 pixel_size=1 direct_init_weight=1 image_model="VQGAN" vqgan_model=coco steps_per_frame=500 steps_per_scene=500 save_every=20 cutouts=128 cut_pow=1.5 gradient_accumulation_steps=1 ``` prior to building this tutorial though, I...

documenting related idea: better support for generating looping animations

I'm pretty sure this is something pytti can already do, just need to build a demonstration. moving this to the pytti-book backlog as a tutorial.
