This is happening (there isn't even a fee for entry) by HOW Design Books:
We’re looking for the best examples of design work that engages and addresses critical causes. This can include paid or pro bono work for non-profits, political causes, social justice, the arts, education as well as self-initiated projects that support the greater good.
Work can be in any medium — posters, logos, websites, brochures, campaigns, naming/branding, etc. We’re especially interested in systemic and/or programmatic solutions, as well as beautiful artifacts.
For all the info go here.
