Finder
Icon, list and column views over one folder tree. The sidebar, the smart folders and the search field all work; the sort headers and the disclosure triangles too.
Each case study is a folder of its screenshots and clips, with the write-up as an RTFD beside them.
Documents
TextEdit lays the write-up out the way it lays out an RTFD: the ruler, Helvetica 12, attachments inline so the phone shots sit side by side. Double-click one and Preview opens it.
Preview sizes its window to the first image and steps through the rest of the folder with the arrow keys.
Dock and menus
Apps bounce twice on launch. Minimize aims the window at its Dock slot by moving the transform origin, so one scale does the shrink and the travel. Shift-click for the slow-motion easter egg.
Menus open on mouse-down, track across titles, and blink the chosen item twice before closing. Sleep fades to black; any click wakes it.
