Many years ago, it was possible to buy small plastic steering-wheels that could be affixed to the back of car seats. The idea was that very small children, who often became bored on long (e.g. more than 5 minutes in duration) car journeys could be fooled into thinking they were driving, by means of providing them with the aforementioned plastic wheel. Perhaps you can get someone to whip up a cheap desktop app whereby employees can adjust the ambient temperature for themselves, perhaps by a nifty slider-bar? This could stop them from whining the equivalent of “are we there yet?” every few minutes.
Or you could just wire up their keyboards so you can shock them at random, to amuse yourself.
Whatever works, that’s what I say….
