this is total bullshit, why should I use a brain with these kinds of egregious bugs in it while the whole time god just sits on his lazy fat ass getting all the thanks and praise for this bullshit?!!! I mean, how hard can it be to code a fix for this, sure, he can invent boobies but can't fix a stupid little thing like THIS?? sure, keep staring at those tits fellows, nevermind that that's not how they really look. fuck god, fuck the brain, I want my money back!!! I refuse to use my brain anymore.

Interesting (no really!)...Maybe the thread title should be F**cked mind thread. It is rather pathetic that it can't even tell when 2 simple shades of grey are the same. Pah! How can you believe anything you see when it can't even something that simple right. Time to go and build some robot implant eyes that do better...

and what can we infer from the sense of hearing?

not audio trickery, but audio fun, putting images in the spectrally processed view of songs:

this is the one I was looking for. watch the video and replay it again as soon as you can. will the scale ever end?

WOW! Something to do with the overtones in the notes?
Or are my ears and mind just really fucked. I wonder if I'll ever be able to identify frequencies again...

I bet that could be done w/ Operator. Hmm..

stare at the + and a green dot appears.

can't see the link right now, but i know it.

i love the shepard tone / risset tones thing.


one of MDA's free plug ins is a shepard tone generator. pretty cool.


the illusion breaks down if you speed it up.




buchla had a couple of cool modules based on this idea as well.

you'd need more than one. I don't think you can pull it off with just 4 tones.




to give a hint, the effect is produced with several sine waves, a fundamental and several higher partials. The fundamental is obscured by making the highest and lowest partial in the sequence quieter than the rest. as a partial reaches the pouint where it is quietest, it is returned to the beginning of the sequence and starts to get louder again, then quieter and then starts over.




this works because the fundamental (the part that tells us what pitch it is) of any tone is usually louder than the harmonics. By obscuring the fundamental your brain is tricked.

As for the squares, the illusion comes from the fact that all the squares around B are darker, and all the squares around A are lighter, which fools the eye.

A big part of that fooling has to do with the instensity of the green cylinder on the right compared to the lack of intensity in the green background.

A fun trick is the ever-increasing tempo trick. I wish I had a recording or could describe it properly. The jist of it is that, with a few good hand-drummers, you keep pushing the tempo higher and higher until you've reached the ceiling of doing your fancy fills comfortably, and then one person (the backbone of the beat) shifts to half-time while everything else continues as is. This half-time beat then starts pushing the tempo to the ceiling again, and as everybody else eventually staggers in on the halftime feel, createing the illusion of an ever-rising tempo . Basically, when you can't play any faster, you start incorporating some half-time riffs, and gradually phasing out the double-time riffs. It's at this point you can start increasing the tempo again. And everybody will follow you or else their hands will fall off. You can do many cycles of this.

Wow, this sound really interesting, kinda the shepard tone taken from frequency to time. Gotta give that a go. If anyone can think of a recording (preferably drummers as described) I'm all ears. Going to half-beat playing drums is already such a nice effect, I can't really imagine what this would be.
