I noticed the similarities to Tornado Cash too in terms of web design, but I just took that as they sort of copied Tornado Cash's design because they looked up to it. Their specialties were in the backend programming stuff for sure, and it seemed that they didn't have anyone rocking and rolling on the web and graphic design stuff, so if that's the case, it's easy and smart to just match the site design to a well known mixer. No need to reinvent the wheel, at least not when they were first starting out. I think if there was any actual relation between Whirlwind and the Tornado Cash team, we would have seen things pan out a little differently and more successfully.
