The avatar feature in OLab3 was remarkably popular, albeit quite limited. On and off, we have explored other approaches to doing this.

With this image, I created an avatar on the iPhone using the Zepeto app, then customized it. Is movable but you need to buy crap to add other options.

The avatar is a wee bit movable on the iPhone so you can screen capture slightly different POVs. Note that the neck is too long, however. Not sure if you can alter that.
