I like very much the buttons in the picture with the outward look gradients :-)
The blue active colour is very amigish (1.3 era) and the grey non-active windows reminds the 2.x and after Amigas. I like them all, just the grey screen bar doesn`t fit very much, I`d like to see a screenshot with a white classic screen bar and the windows with the active blue in outward look.
I just can`t wait to buy it! :-D
Hyperion should definetly include (or implement) in AmigaOS
depthMenu! that way we will not be needing a long bar (which takes much screen real estate) like in M$Windows to bring back and forth the windows.
here is depth menu when you press right mouse button in the depth gadget of any window. (lists all opened windows in the wb, minimize etc are not part of the program, its a module.)

and here in the screen depth gadget
