The Big Story

A developer posted a tiny web tool that lets anyone upload a video and then fly through it in a space-time view. You can adjust how many frames appear at once, slice through time, hide or show future frames, and change opacity so the video feels like a living 3-D sculpture. Think of it like Google Street View, except instead of walking down a street you’re moving through the seconds of any clip you choose. The controls feel like video-game sliders: volume resolution changes how dense the 3-D view is, time-depth decides how far forward or backward you can peek, and synced playback keeps everything moving together. Pre-frame opacity and post-frame opacity let you fade what came before or what comes next so the scene stays clear instead of turning into a blurry mess. Time slice surfaces let you cut the video at any moment and look at that exact slice as a flat layer you can examine from any angle. The tool was built in one evening after the creator saw another post about similar ideas and decided to experiment with Astra, an AI coding helper. This is exciting because it turns passive watching into active exploring, which could help students studying motion in sports, artists remixing footage, or anyone who just wants to see a funny video from a completely new angle. It shows that powerful AI ideas are already being turned into free micro-tools you can try in a browser instead of waiting for big companies to release them. If you have a short video on your phone, you can test the tool right now by visiting the link in the original post on X and uploading it to see the controls in action. The creator even asked for ideas on what to add next, so your feedback could shape the next version. Because the whole thing runs in a browser, no special software or expensive computer is needed. That lowers the barrier so a 14-year-old with a laptop or phone can start experimenting the same day the tool appears. The result feels less like watching a movie and more like holding a tiny, movable sculpture made of moving pictures. Source: x.com

Explain Like I'm 14

You know how when you flip through a stack of photos of the same scene taken a second apart, your brain can already guess what’s happening between the pictures? Now picture an AI doing the same thing, but with every single frame of a video at once. It lines up the frames like layers in a sandwich, then lets you slide sideways through time or forward through space. Instead of just pressing play, you can pause the whole scene, tilt it, or peel away layers so you see what’s coming next or what just happened. The tool doesn’t magically invent new footage; it uses the existing frames and simple math to decide which ones to show or hide based on the sliders you move. That’s why changing “time-depth” or “pre-frame opacity” instantly changes what you see. Volume resolution works like deciding how thick the sandwich should be: more layers mean a denser, more detailed view, while fewer layers keep things light and easy to read. Synced playback makes sure every layer stays in time with the others so the motion stays smooth even when you rotate the view. The result feels like the video has become a sculpture you can walk around instead of a flat screen you only watch. Once you move the sliders, the computer simply recalculates which frames to display at that exact moment, giving you the feeling of flying through the original clip without needing any extra video files.

Cool Stuff & Try This

Make your own iMessage and WhatsApp stickers with ChatGPT ChatGPT can now generate custom sticker images you can save and send in messaging apps. It works by turning a simple text description into a small, transparent image that feels like a personal emoji. This is fun because you can create stickers of your own drawings, pets, or inside jokes without any design skills. Anyone with a free ChatGPT account can try it. Go to chat.openai.com, start a new chat, and type something like “Create a sticker of a sleepy cat wearing sunglasses, transparent background, cute style.” Download the image and add it to your sticker pack in the Messages app or WhatsApp. You can keep refining the prompt until the sticker looks exactly how you want. The process takes less than a minute per sticker, so you can make a whole set during one study break. Because the images come out with transparent backgrounds, they blend naturally into message threads the same way official sticker packs do. Teens who already use stickers to react in group chats now have an easy way to make ones that match their own sense of humor or favorite memes. Source: engadget.com

See how safe self-driving cars really are in real cities A new analysis of New York City data shows Waymo vehicles have fewer crashes than regular for-hire cars when both are measured the same way. The report was updated after the first version had an error, which is a good reminder that data can improve when people double-check it. This matters if you’re curious about the future of getting around without drivers. You can read the updated numbers yourself at the openplans.org link shared in the post. The corrected comparison helps answer the practical question of whether robot taxis are safer than human-driven ones on busy city streets. For anyone thinking about future jobs in transportation or urban planning, seeing real city data makes the discussion feel less like science fiction and more like something that could affect daily commutes in a few years. The fact that the researchers released a revised version shows how important it is to keep testing these systems with fresh information instead of relying on early, incomplete reports. Source: x.com

Quick Bits

ChatGPT can now act like a simple financial dashboard One user connected retirement accounts and PayPal income to ChatGPT and asked it to show net worth, retirement projections, and even how a spouse’s side income has performed over time. It feels like having a basic financial overview without opening multiple apps. The same chat can answer follow-up questions such as “What would happen if I retired in 2035?” and instantly recalculate the numbers based on the connected accounts. Because the tool uses Plaid to link accounts safely, users do not have to type in every transaction by hand. Source: reddit.com

AI video tools are heading toward live control instead of waiting for finished clips Runway is working on a system that streams AI-generated video frame by frame so you can steer it in real time, which could eventually help with robotics or game development. Instead of waiting for a full clip to finish rendering, the model builds the scene one frame at a time while the user types new instructions. This live approach could let creators adjust lighting, camera angle, or action on the fly the same way a director calls changes on a movie set. The company sees uses beyond entertainment, including training robots to understand how the world changes moment to moment. Source: the-decoder.com
