takethesquare.net, a site inspired by the Occupy movement has put out a call for a global day of action on May 12.

The call is out to chapters of the Occupy movement worldwide to march in solidarity with the countries in which uprisings are currently taking place (Syria, Greece, Egypt, Tunisia, Iceland and India to name a few).
