As this post goes live, we are eleven hours and eleven minutes into the eleventh day of the eleventh month of the eleventh year of the twenty-first century. 11/11/11 is being hailed, variously, as “Elevensday,” the Last Binary Day of the Century, and Nigel Tufnel Day, and we here at MAKE would like to invite you to celebrate by joining us in building something, perhaps this weekend, that goes to eleven.  Just be careful not to confuse feet (‘) and inches (“).

Already made a cool Elevensday project?  Or seen one?  Let us know, below!
