I do like this kind of graphics - at least by individual recognizeble animals ! I've seen them for Gorilla's and Elephants but to get the public more involved pictures of the individual would have been very helpfull.
I love the idea too for the exact same reasons. But since Abigail died in 2001 other things have happened with the orangutans and could have been updated. Budi, Kembali and Jingga were born. Molek and Dinding died. Dinar and Jahe have moved on. Im not saying print a new one with each event but when you are 12 years out of date you think they could have afforded to spring for a new one at least after the 3 youngsters were born in the same year.
