In Einstein's light clock thought experiment it seems to me that the clock is conveniently aligned and positioned relative to the observer to offer theoretical proof of time dilation.
The theoretical proof “works” when the clock is conveniently set vertically relative to it's line of travel and it passes the observer at some distance.
But what if the clock was set horizontally relative to it's line of travel, or a vertically aligned clock was moving directly toward the observer?
