Tetris is a very simple game, which I had in my childhood. The aim of this game was to follow the rules and fill each line by elements. I stayed focused all the time.
Brushing your teeth is a daily routine. I first saw a toothbrush when I was a little girl. This activity was full of playfulness for me. My mom told me to carefully brush my teeth and not to miss a single one.
These activities have a lot in common. Therefore I wanted to unit them in my design and to bring a fun to the customer.
