I have also contributed my Progress/OpenEdge version of a 99-bottles program. I was really surprised to be the first one to submit on in Progress, while there was already a malbolge version O_o. I love browsing through that site, just finding new (mostly esotheric) programming languages that I have never heard of before. It made me program a 'fizzbuzz' program in BeFunge. Not the most usefull thing, but actually very fun to do :)
