Motion-Blurred Mouse Pointers?

Dean Siren asks: "Now that GUIs are getting prettier, will they also motion blur the mouse cursor? With most monitors running at 70-90 Hz, the mouse looks a tad jumpy if you follow it with your eyes. Such a feature would make the mouse appear smooth even below 70 Hz, and with all the CPU and GPU clock cycles to spare on most PCs, should not slow the system much. Does such a feature exist in any GUI?" I doubt such a feature exists currently, but do you think something like this would be useful?
