Artists Fabio La Fauci and Daniele Sigalot have been working together since 2005.
For the past 7 years they have been making art based on two characters they invented.
Blue, a sad little drawing with a big yellow tear, and Joy, a similar drawing with a giant smile.
These two artists work with a huge variety of materials in a cool studio that they've named the Pizzeria.
