I almost always need to rotate photos 90⁰ to the right, so I have to tap that button three times. Apart from that, if I have only one way to rotate my photo, clockwise seems more intuitive to me anyway.

[================]
A press of each round button rotates the typing ball accordingly, pressing the space prints the chosen letter and resets the ball to the neutral state. This whole thing should probably be electric lest you'd have to press the space bar by smashing it with both fists.And, you don't have to worry about what to do in the case that someone hits the "rotate ball" button while it's still rotating.
Eh, it's a pretty trivial problem, comptometers have it figured out more than a hundred years ago.
The pilot lights are slightly more useful in those stupid cross-wired double switches that for some weird reason implement a sort of XOR (or sometimes XNOR because why not) gate for controlling a single light: if it's on, then the bulb is depowered and you can safely change it without turning off the entire power rail. But then one day the pilot light itself burns out...
