Because Honda claims to include pixel sized intitials of contributors to their cause on the earth livery of their F1 cars, I assume the cars aren't painted.
So how do they apply the livery to the cars?
YOUR NAME IS ON THE CAR!
Dear myearthdreamer
We have exciting news! Your name will be on the Earth Cars at this weekend’s Grand Prix in France.
Your name will be in 4pt so it’s clearly visible with the naked eye close up, but our clever designers have applied them in such a way that our beautiful artwork still looks the same from a distance.
We have put all the names in columns and like to call it our ‘Roll Call of Environmental Honour’.
In the last few weeks we have made some changes to myearthdream. The biggest change is that we have decided to make donations to the myearthdream Trust optional. The main aim of this is to allow children to make pledges and be part of the project without having to use a credit card, but it also allows us to run competitions all over the world to get more people involved in saving CO2 and saving the planet.
