My husband, Marky, teaches maths to  a group of very intelligent Further A Level students (they are about 17 - 18 yrs old and those super-intelligent whizz-kid types).  Yesterday they were getting a bit overloaded and fraught with the 'hard sums' so he played them the One Plus One video as a bit of a breather! They loved it!  Marky said all the frowns disappeared and they were all smiling and ready to go at the complex numbers again!
