Meet Our Team

IXITID Concepts LLC was formed to create a new generation of immersive, interactive, educational museum exhibits.  The Mars Leap is the first, a showcase for more to follow.  The Mars Leap demands outside-the-box thinking from professionals in fields from computers to theatrical scenery to educational development.  IXITID Concepts will coordinate as design lead, and our core team brings unique abilities to promote success.

Core Team
