Your video reminded me of this selective attention test: https://www.youtube.com/watch?v=vJG698U2Mvo . This Wikipedia article also seems to be related to the phenomenon and talks about the video too: https://en.wikipedia.org/wiki/Inattentional_blindness .

Yes, this is always named in the same breath as my GP post, the gorilla video is a classic. The video I posted much the same thing. It makes you realise how much of what we perceive is really what we think we perceive

It brings to mind the "moving paintings" in the ride wait queues for "Harry Potter and the Forbidden Journey" (a dark ride with a moving car on an articulated arm). I saw those things up close and they had a wonderful canvas texture laid over the screens. It really seemed magical -- though I admit I'm one to give myself over to the magic of theme parks when I can -- and it made me wonder if this effect could be reproduced by using a matte silicone mold of actual canvas or something like that.

As an aside, there is a lot of amazing technology in play in that ride; I read an unauthorized treatment of how the ride works and I was blown away at the systems/mechanical orchestration necessary to pull it off. It's no wonder it breaks down all the time.

It's too bad this isn't on github. I've always wanted to make something similar, but using computational art instead of paintings. My dream is to make a thing that slowly adapts to the room its in, but doesn't seem like a computer hanging on a wall.

Does anyone know where I can learn more about the lighting techniques described here?

Nicely done, though I would have loved to have seen some build pictures. There are a number of commercial players in this market (for example https://frm.fm/ ) which combine hardware and marketplace, and the geek in me would love to see these succeed. I work in e-commerce selling art reproductions and have thought a lot about this. I believe as soon as you make the art ephemeral or changeable, its value (to you, rath…

Interesting, I'd never seen these before. I can't seem to find any info on pricing or availability on Framed's site, though; am I missing something?

Thanks for the explanation, that was great! I imagine you could play Where's Waldo without changing screens. Just "find the next Waldo" on an ever changing scenario. The moment you find one, another is created at other spot. Could be very addictive, although sounds kind of stressfull also.

You could also just have it decide exactly when it wants you to find Waldo. Imagine you had a Where's Waldo ipad app that had 20 different "pages" and you could set the amount of time it takes to get through them all so you could keep your kid busy for a guaranteed minimum time. :)

Or even better, it's listening for you to say "ok, it's time to go in two minutes. Finish up," and it makes sure Waldo appears where the kid is looking just in time.

The downside is when your kid finds out he's going to murder you.

This is also the principle behind foveated rendering ( https://en.wikipedia.org/wiki/Foveated_imaging ) where you only render the graphics in high detail where the viewer is looking, and use a low-res image for the rest with the goal of saving computing power. Big area of development right now for VR!

I am pretty excited about this, I could see this being used with an variant of DLP technology to deliver ultra-high resolution and pixel density only to the area of screen you are looking at.

He says in the article that "Apple did a good job with their monitor", but what he fails to realize is that the panel in that monitor is made by Samsung, and is used in numerous other monitors, such as a bunch of Dell Ultrasharp monitors. These are the exact same monitor, except with a different frame and stand, and are available for a fraction of the cost.

Yea but the integrated quiet computer was also important for his project. Mounting a separate computer would have added a lot of complication.

He does not say this. In fact, at the end of the article, he writes that having the whole iMac is fairly impractical and having a smaller Android system on a chip would be the better solution.

I think the mat around the photo is also rendered, so you can have whatever aspect you want - although a portrait image might look a bit lost in the middle of it. Next step - mount the frame on a motorised bearing so it can rotate 90 degrees depending on the image aspect!

I don't think the mat is rendered. In the video with changing light conditions, you can see how the picture lags slightly, while the mat reacts immediately.

The mat is also used to make the aspect ratio less extreme, so it can't be rendered.
