Your eyes deceive you not. Our own beloved enanocms.org has moved off of the adapted version of St. Patty and is now using a custom theme courtesy of Andrew Harricharan (P55). We're also running the new Enano 1.1.6, including the latest releases of Newsboy and the Yubikey authenticator.
I decided to upgrade to the beta to give an idea of what it's like and because it has features I want to use. Plus it's faster and more secure, and it's just in general a huge leap forward from Banshee.
Yes, it really is based off of the Enano 1.1.x installer UI. People kept asking if I'd ever make a real theme out of it; well, I did (although it was P55 that originally submitted the mockup to our forum). We don't plan to release the theme yet due to copyright concerns as well as the fact that it's not complete (the redirect pages are minimal) and I want to have it as a trademark of enanocms.org. We'll see how it goes and, depending on what the community wants, consider releasing it sometime in the future.
