Made with Uxperior

I’ve added an API to Uxperior that lets you use the desktop capture as a texture, allowing shaders to transform the content. Here’s a privacy filter done in just 50 lines of code (code in the video). I’ll make all filters open-source so anyone can create their own! #MacOS #IndieDev #buildinpublic

The Drones over New Jersey are out of control! I couldn’t resist making a plugin for Uxperior. 😄 #IndieDev #MacOS #AppDevelopment #buildinpublic

Here’s a better video of the vintage TV skin example, this time over the VLC app, since the Apple TV app doesn’t allow screen recording. #MacOS #RetroTech #IndieDev #UIUX #AppDevelopment #buildinpublic

Another example of a Uxperior plugin using window positioning: a focus/relax mode for any app, like the Notes app, for example. #MacOS #Productivity #IndieDev #AppDevelopment #buildinpublic

I’ve added an API to track the position of windows on macOS, enabling Uxperior plugins to do things like create custom skins or interact with window edges. In this video, you can see a skin for the Apple TV app that transforms it into a vintage TV! 📺😊 #MacOS #IndieDev #UIUX #RetroTech #buildinpublic

Thanks to my app, Carsick.app, I can now use my MacBook during my trip to Los Angeles without feeling sick. If you struggle with motion sickness, give it a try! carsick.app

In just a few minutes, you can create animations like the ones from Magic Island for the MacBook Pro's notch. #macbook #appdevelopment #indiedev #uxperior

I’m developing a new Mac App that lets you customize your Mac’s UI with customizable effects powered by my 2D engine. It supports shaders, animations, and full programmability with LUA. I’ll also release the source code for all effects. Let me know if you’re interested! #macos #indiedev #ux

Does anyone else get static on their MacBook when adjusting the volume, or is it just me? #MacBook #RetroVibes #MacOS #Nostalgia #80s #Uxperior 😎

Having a lot of fun adding more controls and experimenting with the Metal shader in my app, Carsick.app.

Carsick.app is like the iOS 18 visual motion cues feature but made for your Mac. If you get motion sickness, give it a try! carsick.app

I love drawing pixel art too, even though I’m not the best at it. Here’s a boss for GoBattle.io that I’m working on. I drew it in Aseprite and I’m animating it with Spine. #pixelart #gamedev #indiedev #GoBattle

Here’s a quick look at my voxel engine! 🎥 This video shows it in much better quality than the last one, where the Chromebook screen didn’t do it justice. Still a work in progress, but it’s getting there! #gamedev #indiedev #voxel #multiplayer

Making some solid progress on my voxel engine! 🎮💻 Currently working on adding multiplayer support. Runs smoothly on a $120 Chromebook so far, but there’s still a lot of work to do. #gamedev #indiedev #voxel #multiplayer
