One of the pieces was this painting. It's a colour wheel, and 3 primary colours as shapes, with the mixes (secondary colours) being different shapes.

I like how it looks kind of childish.
Also, it reminded me of the ultimate extreme sport I invented with Dan when I was younger. Train Jumps.
Massive trains with two carriages going off jumps and going for flips or barrel rolls, and then exploding massively when they hit the ground. The pilot would parachute out, or fly out on a motorcycle
heh.
