Yep, that’s due to his expertise on Blender, a multiplatform 3D modeling tool, well known by designer and graphic-addicts.
The purpose of his flight is share its knowledge during the event “Congreso Nacional de Software Libre”, organized by the Venezuela Linux User Group.
As a frequent speaker of this kind of event, and taking into account the invaluable charism of my brother, if you live in Venezuela (or near there) I encourage you to enroll you into the event.
