Oh wow, this book cover art-piece has the same concept, but even more impressive; the Sun logo has 3 "sun" words in the logo not 4 (I know I also thought they were 4 initially), but this art piece has the word "Al-Khwarizmi" 4 times, one for each edge of the square.

Edit: I can't count, both have 4 words, one word for each edge.
