Not really possible, because how a desktop feels or what can be configured it's hard to show on a website. Especially how you can visually adapt it. And what you can configure in general. Running it from a live USB takes like 5 minutes.
For example KDE is also very close to Windows, but can also be configured to behave more like a Mac. Visually most desktop environment can be themed. Cinnamon just got additions to be able to theme gnome apps globally I think? If you want to use a central dock like a Mac and have running apps at the top, that's just a master of setting that up on KDE.
