Welcome to the documentary in the studio from the BBC World Service.
I am Franny Joey and today we're in the company of the Kenyan artist Mika Obanda.
His mosaics portray the issues facing many in Kenya, but they also have a surprising twist.
They're not created using traditional tiles, but from items that many of us throw away.
Egg shells.
Egg shells can do art.
Not only beautiful art, but deep and very meaningful art.
For the past six years, he's been using these delicate shells,
painstakingly placing the tiny pieces to create his vibrant, personal and activist artworks.
When I'm using egg shells, I'm exploring color.
Mosaica feels very personal to me.
It made me find peace in the moment that I couldn't find peace.
Mika lives and works in Mukuru, a slum area in the south of Nairobi.
Now, about 60% of the capital's population live in slums.
And Mika's artworks often depict the experiences faced by the 700,000 people who call Mukuru home.
So Mukuru, it's crowded.
When we were driving along, we saw a lot of waste dumped on the road.
It can be a difficult place to thrive in.
Does that inform a big part of who you are and what inspires your artwork?
Mukuru inspires my work a lot.
