OLab2 avatars were built on a neat little Adobe Flash tool. Many browsers no longer support Flash. Even in OLab3, we considered changing to HTML5 and a fully integrated system. However, while OLab3 Avatars are popular, we hit a limit on what we could do with them, unless we sank a lot of money into improving them. And there are now lots of other ways to create avatars that you can use in your OLab materials.
