Along with the ACEMS gang Anita Ponsaing, Andrew Stephenson and Jan deGier I helped organize the National Science Quiz, in May 2016.
I helped put the questions for the quiz together, and I also did a warm-up juggling maths show and at the end of the show, I was up on stage to demonstrate an application of topology to the art of dressing oneself correctly.
I'll post some pictures when I get hold of some.
