Heathrow Express ticket machine

Heathrow Express is a train service to and from London
Paddington and Heathrow Airport. The ticket machine enables travellers to
purchase tickets to either destination as well as other underground stops
in London.
The goal in redesigning the machines was to make them
faster and easy to use, and more eye catching in a busy travel environment.
Users can purchase tickets within 2 button presses.

I applied an alternative interpretation of the corporate style to achieve
maximum visibility, and used a selection of alternating colours to prevent
monitor burn while never reverting to the use of a screen saver.
