The Foundry have posted a video from the Mari Launch Event held at the Gnomon School from December 1 2010 where Bad Robot Productions’ Brandon Fayette and Jake Raymor shows their hard surface and organic structure painting techniques using Mari.
As a note the names correctly are Brandon Fayette and Jake Raymor, those may be described incorrectly in the youtube video.

“Brandon Fayette & Jake Raymor from Bad Robot Productions will show us their hard surface and organic structure painting techniques live at the MARI 1.1 launch at Gnomon on 1 December 2010”
