Awareness Raising Spoke Cards Campaign Project?

The truck diagrams need to be simplified colour wise from the ones on MT as they rely on the description.
Just a quick knock up of the diagrams. Maybe the line is a little rhymey but it sort of works at a glance.
Could be the reverse maybe.

I like the idea of using these diagrams in some way, but I think initially unless you know what they are about its hard to identify what is actually going on in these pictures, it could be just be a bit of Mondrian if I didnt know better ;-) Maybe its the colouring...
