HOTW needs your help to create a HOTW logo.  Can you help?

We need to create a logo that is made by all schools that are involved in the project.  
Each school needs to create an image that will become part of the final logo.
What will the final logo look like with all the images from the school involved (remember there are a lot of schools involved)?
Please note that there can only be one image from each school.
Should there be a theme for the images and what could it be?

How will we do this?

Place your ideas in the comments area of this blog by 31st of January and we can then decide which suggestion would be the one that would solve the problem.
