I guess the problem has always been that it is on one hand a conventional looking aircraft while at the same time a one-off experimental. Potentially interesting but not visually attention-grabbing enough for display to the general public (apologies for any apparent dumbing-down). The mathematics context is probably a good use for it, assuming that the aerodynamic considerations will be explained.
Incidentally, its minimum sustained flying speed is given as 33.5 mph and it had a similar speed range to an autogyro. Given a mild wind, it could fly “backwards”.
