Three Rings, the makers of Puzzle Pirates, has just gone live with the open beta of its browser-based, 2D social space, Whirled. Whirled has all the features that have become de rigeur for a virtual world these days: minigames, a personal page-embeddable room for your avatar, purchasable objects, and basic creation tools.
Also, how can you not love a VW where the default avatar is an adorable piece of tofu? Yes, tofu. And it dances. Expect a First Impressions post for Whirled in the near future, boogieing soy critters and all!
