What is Social Design?

To me social design is an idea or design that inspires change in your world.
Here are some links to all the different sites I've been browsing in my search to define social design and inspire me to make a difference:

I thought this sites "Everything is Okay" caution tape would be fun to use:

If anyone knows where I can buy caution tape locally I think it may go well with my DWI Driver expose installation. Speaking of which, here is a link to the most well-known organization for anti-drunk driving, MADD
http://www.madd.org/About-Us/About-Us/Statistics.aspx
They list all the statistics on this page, for example that "three in every ten Americans will be involved in an alcohol-related crash at some time in their lives".
Think about that.
I'm one, are you?
