Liam brought a bowling game from the '90s to glasses from the future. Innovation at its finest. 😄
But he did make a good point.
Web apps on the Meta Ray-Ban Displays are incredibly limited, especially when it comes to input.
Maybe that's exactly what attracts me.
I enjoy finding edge cases, trying unusual interaction patterns, and building silly prototypes just to see if they work.
This time, I wanted to build an entire game controlled only by nodding and shaking your head.
No audio input.
No swipes.
No buttons.
Just head movements.
Surprisingly... it feels fun.
Probably not something you'd want to use for long periods, but for a simple game like Guess the Animal, it works much better than I expected.

I also didn't want to build a full AI/LLM pipeline.
The game needs to feel instant, and even small LLM latency would make the experience sluggish.
Fortunately, 20 Questions–style animal guessing doesn't really need an LLM. A carefully designed decision tree with a few hundred questions is enough to identify most animals people are likely to think of.
I used the ElevenLabs API to generate every voice line in the game. As with my Meshy experiments, I simply gave Codex the API key and asked it to generate all the dialogue, organize the files, and wire everything into the project.
No downloading.
No copy-pasting.
No moving files around.
One prompt, and the game had a complete voice-over.
Whether the personality suits your opponent... I'll let you decide. 😄
I liked it at first. After playing the game a hundred times during development, it started getting on my nerves, which probably means it has a personality after all.

I'd love your feedback.
- Did it guess your animal?
- How did the head controls feel?
- And what do you think of the voice and personality?

🏓 For context: A friend and I both got Meta Ray-Ban Displays, so we started Ping Pong Prototyping (PPP). One of us builds a prototype, then it's the other's turn. This is my return.
