Funny that this thread got revived now, HSA and I were talking about this last night. We have a wire-framed table that he was trying to turn into a Necker cube because I argued with his evaluation of EVP.
You know, any other couple would just argue about dishes or something.

I get that it looks a bit like a rabbit (see Wittgenstein's duckrabbit), but surely nobody actually *believed* it was a rabbit? It's very clearly not.

yah, it's not meant to be truly convincing, more of an actualization of the paper image.this thread could use more of a workout

Shepard tones rule. I want to actually visit an Ames room one day and see what it's like irl and not just in photos.

my version doesn't work quite as well as the video, i shouldn't have posted it!

if you can only see red/green dots moving down, try focusing on the top edge of the image... it reliably kicks me into seeing the left/right yellow dots

No the gif works fine Karl and you can stare at it uninterrupted

With the dots, I can see them moving up/down, or I can see them moving left/right, but they're always red/green. Nary a yellow dot.
MatthewK's checker snakes are pinwheeling inexorably just like they should..

The “Adelson's Checker-Shadow Illusion” in Fuck the NRA’s link upthread is my favorite.
― Mr. Snrub, Tuesday, 17 December 2019 14:31 (four years ago) link
red/green dots is a bit of a cheat - if you follow a single dot going down it stays red or green, if you follow one going across it changes between red and green quickly enough to be perceived as yellow. doesn't feel like there's any brain hacking or uncovering secrets of how perception works.

I first became aware of the Shepard Tone when some scientist chose it as one of his records on Desert Island Discs years ago. Imagine, you can pick just seven pieces of music, and that's one of your choices. Bloody boffins.

Do hallucinations count? For about a year I was having hypnagogic auditory hallucinations (reverse sleep paralysis - being partially asleep instead of awake) regularly, once I figured out I wasn't going crazy I started to enjoy them.
