It's very nice. I wouldn't call it an illusion, though. Our visual system is doing exactly what you would expect it to do. The figures we're seeing are actually being rendered by the grate. It's a clever animation system, not an illusion.
It looks like it wouldn't be too hard to make these with Photoshop and a printer. The overlay looks like the tough part, but I think you can laser print onto overlay material, correct? It would also be a challenge getting an animation that cycles smoothly.
Theoretically, please inform me if I'm wrong because I definitely should not be theorizing - but if the space between the lines are laid out correctly in photoshop - for the bar template one should be able to knock out each animation with the correct spacing. That is too say that the author of this video made it seem like he had the correct spacing info - but any spacing should work - his spacing looks like it worked well with only little movement required in order to trigger the animation. It's basically playing with white space. Tell me if I'm missing something I'd love to give this a shot.
So, I just realized that I've seen this same technique used as animated wind ornaments. The technique is called parallax perception. Well, now everyone has to figure out how to make these in color.
agreed, complacentnation, i would like to see this done 1) in colour 2) supersized scale 3) as light graffiti projected onto large buildings 4) 3d rendered 5) interactive
Yeah I just did this in illustrator and photoshop real quick - quickly laid out a bar grid in illustrator. Took a star in illustrator duplicated it many times (some "movement" at interval opacity - ie object 1 - 100% - object 2 - 95% obj 3 -90, obj 4 - 95 obj 5 - back to 100). Pasted the bar bones star - then the gradated moving image. Duplicated the moving image about 5 times adjusting it's movement in photoshop. Then lastly pasted in the bar, moved the bar down the row knocking out each animation in it's succession. And wham - there it is. Well, this may not work for animating intricate animations but if you're like me and you like creating animated rorschachs then it works, hehe. One interesting thing I'm messing around with, is after knocking the bar out is to paint in something else at 80% opacity when the white had been knocked out -the image then morphs into what you painted in. Also, inverting the image is pretty neat.
Hey, how cool, my 18mth old son was JUST GIVEN a book that uses this... except that each page of the book does this automatically as you open the page (the plastic overlay is embedded into each page like a window that is pulled when you open it.
I just read it to him the other night and thought "Woah, this is awesome"... so yeah, cool to see it here only a couple of nights after I'd seen it 'in the wild'
I thought this was waaayyy over dramatic.
I want that book! What is it and where can I get it?
Same here! Awesome! *art
But Still cool.
