The Semi-Permanent conference is on again this year March 18+19.
Speakers are: Build, Ed Templeton, Marc Atlan, Marok - Lodown Magazine, PlanBSE, Psyop, Qube Konstrukt, Revolver Film, Shift Japan (I like Shift online so this would be interesting), TWiN (Have heard the Baker twins present before. They're really good!), Weta Digital (Lord of the Rings fame so should be really intersting), and The Wilderness.
The Semi-Permanent conference is happening in Auckland, NZ as well on March 12. Speaker list for that date is not up on their website yet.
