I whipped up a new app this morning, based, actually, on a feature of my old AMiga audio processing program HARM.
It's called Yes Session, and what it does is rather simple. Turn it on, and tell it your idea.
When it finds a bit of quiet , it will encourage you and egg you on for more ideas.

This version is all audio, but I'm thinking of getting y talented actor wife and her friends to record some video for me that I'll dynamically play in the same way .
