building @meetblueberry 🫐 and other cool stuff

[Renato Costa @renatoworks]

ok, let's do this: I'm building https://t.co/9byB3ZqH6V with @andrewmichaelsa and will be sharing our journey here. time to cook!

@JannikBuilds @Megootronic @paper I'm blending three layers: video, image and live demo, with scroll detection driving the motion

@JannikBuilds @Megootronic @paper my need for vibes

[Renato Costa @renatoworks]

@Megootronic @paper that's Edgy, a macOS app I've been working on and is close to being released at https://t.co/pL58ERCqGW

@UnnatBak thank you, sir

Someone vibe coded a Mac app that lets you grab images, windows and even your iPhone screen, then move them around your webcam with your bare hands.

On a video call you normally share your screen or hold your phone up to the camera. This turns all of that into something you physically grab and move in the air.

Here's what it actually does:

→ Pull any image, app window or a live mirror of your iPhone or iPad screen into your webcam feed
→ Use your actual hands to grab, move and resize them like real objects floating in front of you
→ Works in Zoom, Meet, QuickTime, OBS, anything that uses a camera
→ Hand tracking runs smooth and low latency, which is usually the exact part that ruins apps like this

Everything runs locally on your Mac. Nothing is recorded, nothing leaves your computer, so you're not sending your screen through some random server like most virtual camera apps do.

It's called Shacam.

biri webcam görüntüsünü elle dokunulabilir hale getirdi.

shacam diye bir mac uygulaması. görüntülü görüşmede ekranını paylaşmıyorsun; bir görseli, bir pencereyi, hatta iphone’unu kameranın üstüne bir nesne gibi koyuyorsun. sonra ellerinle tutuyorsun.

nasıl çalışıyor: kamera ellerini takip ediyor, ekrandaki dijital nesneyi fiziksel bir cisimmiş gibi kavratıyor. iki parmağınla tutup büyütüyorsun, kenardan çekip küçültüyorsun, iki elinle sıkıp yok ediyorsun. minority report’un o havada dosya süzme sahnesi, ama ekstra bir donanım yok, sadece webcam.

asıl güzel yanı kullanım yeri: sunum yaparken slaytı elinle çeviriyorsun, ürün gösterirken telefonu havada döndürüyorsun, ders anlatırken görseli avucuna alıyorsun. kamera artık bir pencere değil, bir sahne.

ekranı yıllardır paylaşıyoruz. ona ilk kez dokunan çıktı.

@rakhul @RoundtableSpace neither, those are for capturing video in, not for being a camera. I'm using CoreMediaIO camera extension, the Apple-supported way to do virtual cameras, so it doesn't break on macOS updates.

On a video call, you normally share your screen or hold a phone up to the camera like a caveman!

Shacam turns all of that into something you physically grab and move in the air.

Pull any image, app window, or a live mirror of your iPhone or iPad screen into your webcam feed. Then use your actual hands to grab, move, and resize them like real objects floating in front of you.

Works in Zoom, Meet, QuickTime, OBS, anything that uses a camera. The hand tracking runs smooth and low latency, which is usually the exact part that ruins apps like this.

Everything runs locally on the Mac. Nothing is recorded, nothing leaves the computer, so you are not sending your screen through some random server like most virtual camera apps do.

Free to try. Pay once to use it as your actual webcam.

The closest thing yet to reaching into your screen and moving stuff around with your hands on a normal video call.

The product crew at the design agency spent six months prototyping a custom hardware rig for spatial presentations. They had mechanical engineers modeling articulating arms, optical engineers tuning depth sensors, and project managers mapping out a $150,000 corporate rollout plan. The goal was to let executives physically manipulate floating UI elements during global investor calls.

The media thought that was the story. It was not.

The reality was a solo developer vibe coding an app called Shacam in his bedroom. He didn't build a custom neural engine or write low-level C++ for spatial depth mapping. He hooked a standard web camera stream into a lightweight, local hand-tracking model running entirely on the user's Mac, bypassing the need for corporate server infrastructure, expensive hardware depth-sensors, or external API relays.

The entire stack runs locally on standard Apple Silicon consumer hardware, utilizing zero-cost open-source computer vision libraries and standard macOS virtual camera logic. By combining basic local image manipulation with consumer-grade hand tracking, the app eliminates the entire multi-million dollar hardware R&D pipeline that spatial computing startups rely on, bringing the deployment cost per user down to exactly zero dollars in cloud compute.

@jinreiyu @iumarmirza hey @jinreiyu I replied to your chat message earlier on reddit, did you get it? hope you saw it and it's all sorted out. please send me a dm here if that's still an issue
