Real builds from real GDG chapters. Two hours, one pizza, one prototype. Filter by track or chapter — or scroll until something makes you want to fork it.
“I assumed building a real-time kitchen assistant would require a complex video streaming pipeline and file uploads. I was amazed that sending raw webcam frames directly to Gemini 2.5 Flash achieved sub-second, structured feedback loops.”
Craft_Faces is a web based live AR mask-wearing application, where you can choose and wear your favorite mask by hand gesture, and snap a shot by voice!
“When I decided to implement hand gesture interactions, Antigravity presented two potential approaches: 2D mesh and 3D mesh, not just one method. It clearly explained how each method works, demonstrated the expected visual effects, and outlined the advantages and trade-offs of each option. This helped me make an informed technical decision. This is very helpful and the spec generation is detailed.”
Turn the random ingredients in your fridge into a custom recipe and a dreamy, AI-generated photo of the finished dish — all wrapped in a Y2K Dreamcore aesthetic that feels like downloading a rare program in 2003.
“How fast vibe-coding tools like Antigravity take a developer from 0 to 1. I was surprised by the level of awareness and detail it displayed after well-engineered prompts.”

“For a first time gemini user it was fun to test the capabilities in a developer friendly environment. I think that in the ~45 minutes we had, I was able to build a fun MVP and demo that satisfied a big paint point in my life, and potentially others. Looking forward to bringing out the max potential out of Gemini and the Google tools as I try to bring this application to the App Store!”
FridgeJam uses Gemini AI to turn leftovers into personalized recipes! Type ingredients or snap a fridge photo for the Gemini 2.5-Flash model to auto-detect them. Ingredients drop into a physics jar where you pick a custom AI Chef for a tailored meal, playing mini-games and guessing jokes while you wait. Get AI-generated food images, download a PDF, or like to save it to your personal recipe box.
“I was surprised by how creative Gemini has become! I prompted Gemini in Antigravity to "go crazy" with a secret feature I won't disclose here, and it delivered one of the absolute coolest parts of the entire project, implementing it entirely from scratch as well!”
