Show HN: A Dalle-3 and GPT4-Vision feedback loop
I used to enjoy Translation Party, and over the weekend I realized that we can build the same feedback loop with DALLE-3 and GPT4-Vision. Start with a text prompt, let DALLE-3 generate an image, then GPT-4 Vision turns that image back into a text prompt, DALLE-3 creates another image, and so on.<p>You need to bring your own OpenAI API key (costs about $0.10/run)<p>Some prompts are very stable, others go wild. If you bias GPT4's prompting by telling it to "make it weird" you can get crazy results.<p>Here's a few of my favorites:<p>- Gnomes: <a href="https://dalle.party/?party=k4eeMQ6I" rel="nofollow noreferrer">https://dalle.party/?party=k4eeMQ6I</a><p>- Start with a sailboat but bias GPT4V to "replace everything with cats": <a href="https://dalle.party/?party=0uKfJjQn" rel="nofollow noreferrer">https://dalle.party/?party=0uKfJjQn</a><p>- A more stable one (but everyone is always an actor): <a href="https://dalle.party/?party=oxpeZKh5" rel="nofollow noreferrer">https://dalle.party/?party=oxpeZKh5</a>
Show HN: Trains.fyi – a live map of passenger trains in the US and Canada
Hey all! My train the other day was delayed and I got curious where they all were at any given time, so I built a map and figured I'd share it.

Show HN: We made an interactive coloring experience for kids
Hi HN community!<p>Proud to have recently become a founder myself and now to submit a "Show HN".<p>We are Dibulo, a young startup which is on a mission to redefine coloring sessions for kids! We have built our first worlds, sold our first coloring books and now we want to let the world know about us :) So far we have been praised by parents, and also got pretty good feedback from institutions like daycares and elementary school teachers.<p>What sets our coloring experience apart? Not only do we bring vibrant templates on paper to life on screens, but we also introduce a captivating group activity. Picture this: kids enthusiastically coloring away, their creations showcased prominently on a big screen for all to admire.<p>For us it is crucial that the user experience is smooth and easy. Our platform works in pretty much all modern browsers and on all major devices (PC, laptop, tablet, AndroidTV / FireTV). Setting up a coloring session on Dibulo takes less time than a kid can color our templates and uploading is as easy as snapping a picture. You can even share the coloring session with your family and friends and if they like they can participate and upload their drawings too (remotely).<p>Feel free to download and print our free templates and try them with your kids / nephews / at your daycare.<p>Thank you for checking us out! Looking forward to receiving feedback!

Show HN: A game to memorize scale degrees on the guitar fretboard
Hey all, posted a similar game a few months ago for memorizing the notes of the fretboard.
