Kitchen bubbles

For the backsplash of the kitchen in their new house, my brother and his girlfriend asked me to make a design based on bubbles and the colors green and grey. After trying several design options and playing around with the bubble size and the behaviour around the edges, we decided to go for a design with several transitions taking place from bottom to top: smaller bubbles, less bubbles, lighter colors, and more irregularity in the bubble shapes and positions. It is printed on the back of a 270 by 60 cm glass plate, and reflects very nicely in the induction cooking plate.
