Idea Development:

...still bouncing ideas around in our group, we decided that we don't necessarily need to focus on getting the drivers attention, but could use traffic lights in another way to trigger our sensor. When traffic lights are red, the 'walk' sign is displayed. We could us the light from this signal to trigger our sensor, and in turn project an image onto the zebra crossing. I like this idea as it has more potential with what we can achieve.
