Very Classic Concentration!
TSTO created this for Vuoden Huiput (VH) 2010. VH is Finland's yearly design awards for best in advertising and graphics.
Best if I let them describe the process of creating this: "Together with a programmer we created an application that transformed any written word or sentence into a rebus, an allusional device that uses pictures to represent words or parts of words. In English, a rebus often uses homonyms, as seen in the classic IBM logo consisting of a picture of an eye, a picture of a bee and the letter M. However, homonyms are rare in Finnish language, therefore a rebus was constructed from a list of some 5000 words with the most used syllables and matched with an image search result from Google." Interesting, huh?
