Hi @ADev !
We don’t have an example project yet, but my Kotlin template could be a good starting point: GitHub - Stefterv/processing4-kotlin: A minimal example on how to run Processing within Kotlin
The Processing DE also uses Compose Multiplatform so that could be an inspiration.
The only thing I have not tried yet is to see if I can hook a Compose frame into the Processing window, but my intuition would says it could be possible.
