I make cardboard furniture

The statues I sculpt weigh only a few grams

I pay you back for recycling

I turn your dance moves into kilowatts

I put your computer to work for a good cause

I help paraplegics to walk again

I detect cataracts with a mobile phone

I created Neighbour Day

I teach people to read with dominos

I created the world's simplest toilets

I trade your trash for organic food

I use the forest judiciously

I created an open-source machine to make natural dyes. 

Relax on my carpet of nails

I created universal eyeglasses

Clip Villa Shamengo COP 21

I created Flash Mobs

I make you laugh out loud

I transform sacks of fish food into chic shopping bags.

I created a universal language for the deaf community
