We used to have a Mario hat and a showcase of Mario's games with Mario's picture on it as the logo of the wiki, didn't we? I actually liked the one with Mario's games more, to be honest. More colorful, and even though it's outdated, it has some charm to it.
I remember this logo, but I don't remember it being used on the wiki. Was it before my time or was it one that was considered but not implemented? I actually really like it, but I just don't think it was ever used.
