Getting "state from something executing" depends on the platform (android/ios/linux/macos/windows). But for security reasons, you usually won't be able to access the memory of an arbitrary program. You could sample the first n-bits from a binary and use it to seed some kind of generative art tool though. Or you could do something with the sequence of states if you can launch the app with debug tools (gdb, etc.).
