Has anyone seen this before? I thought it seemed pretty familiar. My apologies if this has already been posted. I searched for it and nothing came up.

IMO only the first picture is really all that trippy (the cat is sorta). But I think this would be really cool if it were combined with an image or animated sequence that was processed through DeepDream.

Why don't you run it through deepdream?

It looks like they simply rotate the color palette for a particular image.

Indeed, the manipulation does seem extremely simplistic, but it might perhaps offer an insight on how the psychedelic effect may or may not be achieved. I find that in the case of my psychedelic experiences, that holographic or patterned overlay can also be responsible for image distortions. I would say that all of the examples in the video were somewhat reminiscent of the texture breathing effect. It is typically one of the first visual effects to be noticed on all of the tryptamines. The speed with which more complex visual effects tend to come on, will usually be largely determined by which tryptamine was used, and in what fashion.
