TubeTalk Kiosk Sketch

I roughly sketched how the Tubetalk pins kiosk should look like.
1. It should have boxes with different colours on the side for pins of correspondent colour and interest;
2. It should have a table for commuters to be able to customize the pins with a comfort;
3. It should have free pens/markers, so the commuters have something to write their text on the pins with (markers probably attached to the table);
4. It should have an explanation poster, so the commuters know the idea of the campaign, know which the meaning of the colours etc.
Poster can also call for the commuters to join the campaign;
5. It might also have the 'I found it!' board, where the commuters will attach their pin after they have found what they were looking for or if their 'tube talk pin' journey was resultative.

There also might be some volunteers involved, standing next to the kiosk and helping people know more about the campaign, as well as trying to attract more people to join in.
