Inspired by the adjective animal-noun meme suggested by McDowell, I thought of the
purplepenguin.com
but there is a site using that name already :/ though it still has "lorum ipsum" text all over the place, so they may yet go bust and leave the domain free ...
There is also an existing http://orangepenguin.com/ but http://auberginepenguin.com/ is available, though it is doesn't trip off the tongue the way purple does ...
