Tateru Nino has been doing some fantastic posts on Massively lately, and has dug up a real gem in "Peering Inside: Whither avatar puppeteering?". Digging into the avatar puppeteering project which has been more or less missing in action since 2006, she finds that Jeffrey Ventrella, the main man behind the project, left the Lab in August last year - and the project has been "on hold" (which usually means "dead") since then.
Good digging from Tateru, who's posts on the whole trademark debacle have also been essential reading.
