This year was my first MIT Reality Hack and it was incredible. My team, team Amadeus, made an interactive application that teaches you about waveforms via a repurposed Guitar Hero controller and an ESP32 connected to Unity via Bluetooth. Looking into the VR glasses, the Quest 2, you are immersed in a sea of particles visualizing the transformations of modulated waveforms.<p>The particles are made with Unity VFX graph, the synth was made with CsoundUnity a wrapper for Csound, and the Quest connected to the ESP32 via bluetooth using the Singularity package by MIT VR/AR club.
