Twelve over twelve

After the success and gratification of 26 in 52 (which profiled all twenty-six letters of the alphabet over the 52 weeks of 2010), I have decided to undertake the next logical project, involving another one of my obsessions: numbers.
By the last day of each month in 2011, I will compile and share everything I can about the universal numbers 1 to 12. I'm not entirely sure this will progress, but I look forward to the journey.
Twelve over twelve - here we go! First post on zero and one coming soon...
