Does anyone know of any hydraulic or pneumatic schematic simulation tools like this? I've been wanting to make something like that for a number of years now, but haven't yet had the chance. Also, I'd be curious to know more about the team behind EveryCircuit, what approach they took to managing simulation logic (eg: discrete vs continuous), and other nitty-gritty engineering details.
