“D1G1TAL CHR0N1CLES” by the Georgean duo Levan Patsinashvili and Davit Babiashvili is a series of pictograms depicting major historical events using cleverly designed fonts. The designs are puzzling, educational, and eye-pleasing at the same time. Can you guess what happened in the years 1250, 1912, and 1975 by examining these three images?
Well, the sequence {1, 1, 2, 3, 5} is the Fibonacci sequence, and 1250 is the year the famous mathematician died. The sinking number “1912” hints that this is the year the Titanic crashed, and the funny “97” which resembles the Windows OS logo symbolizes the founding of Microsoft in 1975.
Below, we are presenting Levan and Davit’s entire series, consisting of 52 designs, in chronological order. Which ones are your favorites and how many events can you recognize?
