A downloadable AR butterfly

Butterfly AR was created for the Reality Hack MIT after-party, during the UnitedXR Europe event in Brussels (December 8–10, 2025).

The Butterfly Project is an interactive AR art piece that can be set up anywhere. The user is surrounded by a swarm of butterflies flying around them and has the possibility to interact with their own butterfly, which follows the left hand for as long as they want.

The goal of this experience is to take you back to your childhood memories, to slow down and contemplate your own space filled with butterflies, before starting to play, dance, and contemplate alongside your new butterfly friends.

The experience was developed using Unity and the Meta Quest SDK, entirely through a remote desktop workflow using Parsec. Parts of the code were generated with the help of Google Gemini AI to gain time and improve efficiency.

This is my very first Meta Quest 3 AR passthrough hand-tracking experience as a solo dev!
