If you’ve been following the MySpace Layouts trend, you might already be familiar with Zwinky, a brand that seems to appear frequently on those sites. Yesterday, Zwinky launched officially and claimed more than 2 million unique users - not bad going when you consider that the service only began its beta in June. Zwinky is owned by IAC, most famous for its Ask.com property.

Like WeeMee/WeeWorld and Meez, Zwinky provides portable avatars to post on Facebook, MySpace and other social networks - changing your avatar on the service automatically updates it elsewhere. Unlike rival services, avatars are created using a toolbar that bundles a bunch of other IAC services: Smiley Central, Cursor Mania, Popular Screensavers, the MyWebSearch search box and Search Assistant. Experienced users should be dubious about downloading this stuff - although not malicious, the toolbar adds a large number of features that you might not want. Once downloaded, the toolbar lets you choose from a selection of hairstyles, eye colors, skin tones, outfits, makeup, accessories and backgrounds. What’s more, Zwinky provides MySpace-style profile pages that are totally customizable: drop in a MySpace layout, add YouTube videos, send “Znotes” to other Zwinkies and more.
