This is built on the work of many people who wrote the tools, did the research and recorded the sounds, and shared them. Each is listed here, with a link to their own work.
Each painting opens as a place you can enter and fly over freely. Its light and dark are read as land, so every ridge and hollow is the paint itself. The sky over it is real and the weather where you are.
It runs in an ordinary web browser, with nothing to install or buy, the same for anyone with a link.
