I have built the Numode logo out of bricks for use as a display at exhibitions and in my office window. Numode.net has been the url for my online since about 1999 and this must be the 100th variation of the ‘nu’ symbol. Failing the italicisation (if that even is a real word) of the actual logo I am very pleased with the results.
It required four of the classic Brick, Arch 1 x 5 x 4 piece which, as it turns out, is a very rare to come by in Green. It only ever appeared in one offical Lego® set, a Harry Potter set circa 2005 and cost me about €4,- a pop!
