As an artist who explores mathematics through multi-dimensional art and works with mathematicians, can confirm, they find us all dumb. But! I have genuinely intrigued a few too.
If the maths kiddies get too much, paint/draw/whatevs a spherical cow - do it in the style of Mr G Larson (don't forget the light frown). If they don't get it then find another mathematician - they are quite common and herds of them are reasonably easy to find.
If you need to encourage one to eat from your hand, try a fourth order differential equation with e and i in it as a tempter and work on from there. Be very careful of straying into physics - if something useful comes up they are known to scatter. Very skittish, your wild mathematician.
You are not dumb - no-one is dumb. You have a voice and are demonstrably not dumb and the dumb have hands and are hence not dumb. If the dumb don't have hands then it gets complicated but it is possible that they might not be dumb. Dumb as a synonym for stupid is dumb. Please don't be dumb and use the term dumb.
Funny you mention Rubiks cube, here is a project I worked with 2 fellow computational artists on. We generated the form using open cas.cade, then machined it all on a 5 axis VMC, then assembled with magnets and a steel ball barring that I pulled from a ship engine. Carrol and Ruza if yout out there, I miss you :(
