The footer of cymascope.com links to @CymaCymascope on X. That account was created on 26 August 2017, has gathered 437 followers, and has posted zero times. A second handle, @CymaScope, was created in February 2015, has three followers and has also posted zero times.
This is a small finding with a practical use. The CymaScope is the instrument most often named in cymatics articles, and writers reasonably go looking for a primary source to cite or contact. On X there is nothing to cite. The live channels are the website and the Instagram account @soundmadevisible, which has 265 posts.
If you need a statement from the project, use the site or Instagram. Do not describe the X account as a source; it has never published anything.
