Spinal Tap fans will want to turn it up today, because it is the eleventh of the eleventh of 2011, or what one Californian group has dubbed Nerd New Year.
The group is holding a huge street party – supposedly with 1111 people – to recognise the date, which in six-figure form (11/11/11) is also a binary number.
The party will include a robot hackathon as well as a hackathon for veterans, in honour of Remembrance Day, which recognises that on November 11, 1918 at 11:00am an armistice was signed between the Allies and the Germans, bringing an end to World War I.
Learn more about the street party here or follow it via the hashtag #NerdNewYear. Otherwise, take a moment to watch the amp scene from Rob Reiner's classic mockumentary, or even listen to The Humans Are Dead by Flight of the Conchords, complete with binary solo.
