An article in Tuesdays Guardian (10.2.09) included, in the G2 supplement an item about the use of LEGO as a means of communication. In view of the CS lecture on Monday I thought this provides an interesting twist on the subject of "Symbol-based writing system".
The author, Christopher Niemann, an American born Illustrator and Photographer, currently based in Berlin, claims he came up with the idea for his LEGO symbols whilst trying to entertain his sons through the long winter evenings.
This is the link to the Guardian article and this is the link to Christopher Niemanns blog, Abstract City in the New York Times, the origin of the piece. This is just one of many LEGO symbols he has designed. There is now a huge following of fellow contributors to the symbol gallery.
