From what I Googled two days ago he withdrew from all online activity in around 2002/2003. He still can be rarely seen on the Animation Nation Forum. The last time he was there was in January this year confirming that he is still working on his film, "Elysian Tail" and that there "is a few more years ahead before it's completed". There is 20 minutes of the film completed. I found some screenies too, and a clip.
I'll get the clip in a min.
