> Making art is hard. But art is mostly about surfacing the inner world, and only in part about skill. It’s unfortunate that art selects so strongly for skill. Not to sound like a luddite, but I do question the idea that the skill gap is merely an inconvenience. I suspect learning how to paint or make music changes something in yourself which teaches you some deeper life lessons. I've heard the phrase (paraphrased):…

I think he's on the right lines with "surfacing the inner world", but that's why I see this as more wallpaper than art. He's not doing a deep dive into his own psychology and hauling up pearls; none of these images have that property.

Does the totality of the project have that property? That would be less clear, but IMO, no. I see it as technically driven, not psychologically driven, although I can see how you could write an artist's statement that claims it was (it's about mirrors, after all, which are hugely symbolic).

To be clear I still like it, and if I'd done it I'd be proud of it. But it's more artifice than art.

(If I was him, I'd slow the frame rate down, not speed it up - work with the technical limitation, not against it. Have the system only display "good" images, and not update the display until another "good" image is generated. The code that decides if an image is "good" or not would be the most interesting part of the system, and could fairly be said to embody the artist's intent, and so cross (my own personal) threshold into capital-A Art.

I'd also experiment with buffering the image stream à la _Light of Other Days_ by Bob Shaw.

Oh, and as Halloween is nearly with us, the temptation to occasionally inpaint a figure standing behind the viewer would be massive.

Idle thought: to get some stability in the image, would it be possible to have an LLM generate random video filter code, instead of random images? "Write me a video filter that makes the input video look cubist". "...like an oil painting" "...with a Flash aesthetic". etc etc. Every time a filter gets generated that doesn't actively crash, swap to it. No idea if that's feasible or not.)

This goes opposite to the saying "Experts say it cannot be done; amateurs accomplish it every day.". Sometimes it's good to have someone with fresh eyes looking and something and not be shaped by decades of prior history.

> "Experts say it cannot be done; amateurs accomplish it every day." I love this because I seem to encounter situations like that every day. Who came up with this saying? Recent example: This guy asked a very simple question about something that's commonly done in industry (wiring two power supplies in parallel and balancing the current between them): https://www.reddit.com/r/AskElectronics/comments/1g84zd7/usi...

I guess there's the armchair expert and the actual, real expert and these two are completely different beasts. I wouldn't feel comfortable with this guy's usb-c setup but probably not for 'it's all going to burn down' reasons, more like 'the connection will get loose somewhere and I'll lose my work'.

He posted the photos as soon as he got it working; It's obviously not his permanent setup. My point is that he posted it on the same day that ~60 people claimed this was somehow a difficult task.

Everyone in that thread pretended to be an expert despite being clueless. This is normal, but you'd only notice it if you're familiar. Also see Gell-Mann amnesia effect

Nice! I peeked at the code and thought I’d share a few tips for improving the low frame rate: Base64 encoding the JPEG bytes will increase payload size up to ~30% and burns CPU cycles on both client and server. This is unnecessary, as Websocket protocol can send binary payloads (doesn’t need to be text). Consider removing lossy jpg compression as well, ie just send the raw RGB bytes over the network. Then on the serv…

Ok, but I wonder if it really needs to be real time like this? Wouldn't it make more sense to have some kind of button: somebody makes a pose, takes a picture, the picture is run through some kind of transformation and comes back as a painting that stays there until someone takes another picture? Wouldn't the illusion of art be better that way? (It would not be a "mirror" anymore though.)

I was not aware of that specific formulation but there's a maxim by Mark Twain that says "They did not know it was impossible so they did it".

I think this would be cooler if the camera was somewhere different than the frame. Looking at an artistic mirror seems a little boring. Maybe make a 2nd one, and put it in someone else's house, and then feed the camera from one into the other. So you can look at the 'reflection' of someone else and have these little moments where you're both looking at the picture at the same time. Heck, make many so you never know w…

that's a good idea but something completely different than OP wanted to accomplish. i remember that this has been done already as an art installation in public places so people could see - and interact - with others from around the world. edit: like this here - https://www.inavateonthenet.net/news/article/vc-art-installa...

> an art installation in public places so people could see - and interact - with others from around the world

Sure, and it wasn't long before this happened:

> It took less than a week for people eager to share their ‘assets’ with the world to shut down the visual portals set up between the cities of Dublin and New York on 8 May. Although the project was aimed at bringing people together and connecting cultures, a few visitors to the locations have decided to take the invitation of getting to know others to a whole other level.

(One wonders why flashing is such a big problem that the whole installation needs to be shut down; but it seemed quite obvious from the start that people would try to do this...)

FYI, the link to the frame used to mount the display just blocks you: https://www.leroymerlin.fr/produits/decoration-eclairage/dec... For those curious, it's a MILO 21 x 29.7 cm black frame. These links work for me: https://www.leroymerlin.pt/produtos/decoracao-e-tapetes/mold... Also, the screen he uses (HMTECH Raspberry Pi Screen 10.1) is pretty hard to find. Do people have other good recommendations for screens wit…

The screen is available on Amazon? But it's a touch screen, which seems overkill; any screen would probably work? One can always build a custom frame around it.

I don't have anything to say about the artistic value, but as a part-time tool collector with dreams of being a handy person, this passage was the most interesting: I used a puncher to cut a hole in the frame’s cardboard for the camera (drills didn’t work). I would love some more detail, or just people's interpretations ... in what manner can a drill fail to "work" on cardboard? There can be issues with tearing, perh…

My guess is he tried with a wood drill bit, which will tear cardboard and make a big mess. For cardboard, or plastic, you need a metal drill bit.
