The pictures in the pretty-box when searching for the greek letters, e.g alpha, beta, gamma, lambda, currently display the historic variations (e.g lambda shows Phoenician Lamed), not the greek letters themselves, as could be expected. 

While that's an interesting look at the history, I believe that's a bug, as the text on the side says "Lambda is the 11th letter of the Greek alphabet", thus the picture is quite misleading.
