A while ago I was somewhat involved in the launch of the unofficial Welsh Bands Forum, and designed a mascot to be used in the site’s graphical identity. Sadly the forum is becoming a bit of an abandoned project but may be revived by its owner sometime in the future, at which point the designs will be waiting for him.
I’ve always been fascinated by the Welsh flag (and for that matter flags in general) – a dragon is so much cooler than some boring crosses. The best world flags have out-of-the-ordinary designs specific to their country and cultures and are less likey to be confused with other national flags. For example, the Ivory Coast flag bears a resemblance to Ireland’s, and Niger’s resembles India’s somewhat.
It’d be an interesting project to create some flags for online nations, countries that don’t lay claim to any specific areas of land, only cyberspace.
