Yes, linked here in Contour thread. AFAIK they’re taking inspiration from it but how near or similar Contour will be is unknown still.
edit: found the comment saying it’s on the inspiration list link - hope the project is still alive and running
Cool, thanks. Yes, waiting for updates on Contour then.
