ADVERTISE AT BOING BOING!
Here's a great optical illusion (click above to see the animation) -- when you blink fast, beautiful mandalas emerge.
(Thanks, Fipi Lele!)
I don’t see why blinking changes anything. Blinking or not, they’re visible.
That’s pretty much what my eyeballs looked like when I rode my motorbike to work this morning, here in balmy London.
Curiously, this gif is tileable – and it looks way way trippier when used in fullscreen mode. I wrote this in a couple of minutes: https://dl.dropbox.com/u/3578124/_projects/mandala.html
It’s actually /not/ tileable. This is a graph of some sort of projection of Penrose tiling; once you know that, finding the seams in the gif you made is straightforward. Yours looks lovely, however.
Pardon me; it’s a quasicrystal diffraction pattern. More goodness here:
That IS cool. I’m not sure how I take the blinking thing tho. This might be by the same guy : http://fleen.org : it looks similar.
Holy hell, didn’t anyone consider a migraine trigger warning?
As a migraine sufferer, I find the concept of trigger warnings offensive.
I’ve always felt that those who take offense when none was offered should be treated as thieves.
Is this the product of a Reaction-Diffusion system?
In a manner of speaking, since it’s a quasicrystal diffraction pattern, which is caused by the diffusion and self-reaction of light with itself (by waveform cancellation or amplification) through a crystal.
Hrm, if I have my contacts out and look at a point/coherent light source in a dark room (e.g. single LED), I see patterns much like this. I wonder if that’s light bouncing around my lens.
My expertise is in enjoying this and I am very good.
My God, it’s full of stars.
Is it a “Penrose Tile”?
Yes, see bardfinn’s link in an earlier comment.
I love quasicrystals about as much as I love the Steady State hypothesis.
Well this is weird. I’ve had this Twitter profile picture for years now…
