5 Gemini 3 Vibe Coding Projects That Will Blow Your Mind

Ever since its announcement last month, Gemini 3 seems to be everywhere. Google is pushing its latest AI model (and its subsets like the Nano Banana Pro) through all possible marketing channels, part of the reason why we can see its LED billboards, posters, online ads, and even commercials during the India vs South Africa screening. And why not? After all, Google has managed to empower the new Gemini 3 with so much firepower that it is practically impossible to find a limit to its everyday application. Case in point, a bunch of recent tweets that highlight how Gemini 3 can magically enhance any project with its vibe coding, you may be working on.

To give you a hint, here is the latest project that’s going viral – a 3D interactive screen where you can move particles with your hand movement. Seems straight out of Iron Man, right? Well, if you think such a tech is years to come, think again. Because it is not just already here, it is now being done with a single prompt in English.

The power of Gemini 3 in all its glory.

Here is a look at all such projects that are sure to blow your mind, given their effect and the ease of execution with the power of AI.

1. A Mind-Blowing 3D Interactive Particle Screen

Remember the screen savers we used to see on the computer screens till about a decade back. How the particles would fly into one shape and onto another in one seamless flow. Well, now you can not just see but control them too. Courtesy – three.js and Gemini 3.

A recent visual project going viral on X lets you control a screen of 3D flowing particles with hand gestures. Though fancy, it is not even remotely as difficult as it may seem. All because you now have the power of AI to do the coding part for you.

Simply head on to Gemini 3 on the Gemini website or Google AI Studio, and enter the following prompt:

Prompt 1:

Create a real-time interactive 3D particle system with Three.js.

requirements:

– Control the scaling and expansion of the particle group by detecting the tension and closing of both hands through the camera.
– Provide panels that can choose hearts/flowers/saturn/Buddha statues/fireworks and other templates
– Support the colour selector to adjust the particle colour
– Particles need to respond to gesture changes in real time. The interface is simple and modern.
– The interface is simple and modern

If you wish, you can even tweak this prompt to your liking, as I did here –

Prompt 2:

tweak the code for a single-hand use, with the following instructions –

raise the hand = zoom out
lower the hand = zoom in
move hand left = rotate clockwise
move hand right = rotate anticlockwise

Once done, simply save the HTML file and run it on any browser. Once you are in and your camera is turned on, the webpage will let you control a 3D particle animation with your hand. Here is a look at how it works:

Thank Gemini 3, for making this possible. But not just yet, as there is ample more you can do with it, like –

2. Learn Sign Language With Confidence Score

I am sure many of us have wished to learn the sign language at least once in our lives. What if we had a live tutor for the same, that would not just teach us but also analyse our sign language in real-time as we practice it? For an X user, Gemini 3 recently made it possible with a single prompt.

Within 5 minutes of vibe coding with Gemini 3, X user Allie K Miller was able to create a video-enabled app for sign language. The app included features like confidence scores, sampling settings, and tips. As can be seen in her video, the app lets you learn sign language with proper on-screen instructions, as well as a video recording ability that maps your hand gesture with a confidence meter for accuracy.

3. Have Your Own AI Podcast Host

Yet another tweet by X user Zara Zhang shows a video recording tool that shares real-time questions and prompts to get your creative juices flowing. The app basically acts as a podcast host in real-time, listening to your answers and generating follow-up questions or prompts, as if you are in a podcast interview. It is basically meant to help you be more spontaneous in an interaction or on camera.

Zhang highlights in her tweet how Gemini 3 comes with native integration with the camera, which makes this entire app possible. The app she built even lets her download the video interactions once she is done, adjust the video aspect ratio, or get AI-generated video ideas. You can have a look at the tool and its working here:

4. A Super-cool Multiple Windows Portal for Webcam

With Gemini 3, X user Alvaro Cintas created a ‘Portal Windows’ app that looks super cool in action. The app basically maps a single webcam feed across multiple floating windows. It sort of looks like actual windows from which you can see across, as someone moves across their webcam. With such multiple windows for webcam streaming, online video catchups will never be the same again.

Even though there is no practical use case for such an app, the fact that Gemini 3 made it possible with a single prompt goes on to show the might of Google’s latest AI model with vibe coding. Check out Cintas’ super-cool Portal Windows app in the video below:

5. One for the Artists: 360 Panoramas with Nano Banana Pro

Nano Banana Pro has unarguably been the biggest update in the world of AI image generation and editing so far (read its comparison with Grok Imagine here). With the new model now being powered by Gemini 3, Google has managed to unlock a whole new world of possibilities. X user Miguel demonstrates this in his tweet, where he was able to generate a near-perfect 360-degree panorama of the South Pole, complete with aurora lights and a kingdom of penguins, using Nano Banana Pro. If you have ever used an AI image generator (if not, try any of these 10), you know how big a leap this is.

Miguel also notes how this feature of Nano Banana Pro has managed to cut down hours of effort and hundreds of dollars in training LoRAs for SD 1.5, SDXL, and FLUX. Check out what Miguel was able to generate, here:

Conclusion

If there’s one takeaway from all these wild experiments, it’s this – Gemini 3 has turned vibe coding from a geeky dream into a real superpower. You no longer need to spend weeks mastering frameworks or debugging endless lines of code. One good prompt, and you’re suddenly building interactive 3D screens, sign-language tutors, podcast co-hosts, and even magical webcam portals.

It seems to be a new era of creation where the difference between imagination and working software has been reduced to a few minutes. All of this, thanks to Gemini 3 (and other Google AI drops that you can check out here). The only question left now is: what incredible project will you bring to life next?
