I make cardboard furniture

I created metro maps for the visually impaired

I use oyster shells to make paint.

Come on over, my neighbour’s making dinner

I’m coming to stay with you

I train rats to detect landmines

These wood bricks don't need nails, screws, or glue

My technology reduces maritime shipping emissions

My radio show is run by crazy people

I recycle plastic bags in New Delhi

I created the world's simplest toilets

Use your eyes to heal your trauma

I created the world’s largest work of art made from recycled objects

I offer a roof to millions of people

I created Clean Up Day

Our students pump fresh water on the playground

I grow vegetables in the heart of the city

I put your computer to work for a good cause

I grow the packaging of the future

Un chantier complètement fou !
