London 2012 Logo by Saeed N. Fotuhi

it's inspired by the world-famous london underground network. the blue ring is an o for olympics the other four are 2012. the green line and the ndon is an L, and the little circle is the famous underground symbol for a stop as well as the first o of london. the ndon is written beside the stop as the names of stops are written beside such symbols on the similarly-coloured underground maps.
