Building a New Medium

From possibility to practice.

When I joined Sphere in August 2023, the Exosphere had been displaying permanent public content for only about a month. The team had already spent more than a year pioneering the medium, yet its creative language, workflows, and best practices were still evolving in real time.

Executive impact at a glance

Why this work mattered.

Creative leadership and production systems for a newly launched medium: signature celestial work, shared review and mapping methods, and two pending patent applications within a broader tools contribution.

Role Lead ExoSphere Content Creator

Content designed for an unprecedented architectural display.

Intellectual property 2 pending patent applications

Associated with ExosPreviewer and ExosMapper, two examples of a broader tools contribution.

Sphere productions 20+

Creative contributions across uncredited Sphere productions and signature public moments.

Operating model Reusable systems

Tools and practices designed to outlast a single delivery.

My contribution

I lead Exosphere projects, develop looks, and solve production problems across creative and technical work. ExosPreviewer and ExosMapper are two examples among many tools I have built or helped deliver.

01

Finding the real problem

The medium had launched.
The practice was still being invented.

The team had already proven that compelling content could live on the world's largest LED canvas. The next challenge was making that success more repeatable: learning what translated from preview to reality, shortening feedback loops, removing recurring friction, and raising consistency as the work became more ambitious.

I brought more than two decades of experience from visual effects, animation, immersive design, and emerging technology. My role was not to claim the beginning of the story. It was to help accelerate the next chapter.

Redefining an icon

The Moon,
reimagined.

The shared practice came into focus through the work itself. The Moon shows how scientific source material, reconstruction, and creative judgment came together at architectural scale.

The Exosphere launched with a Moon. My assignment was to make it unforgettable.

From scientific observation to emotional experience

The goal was not simply a more accurate Moon. It was a Moon people believed.

I used Lunar Reconnaissance Orbiter imagery as the foundation, then shaped lighting, contrast, motion, and surface readability for the Exosphere. Scientific accuracy guided the work; creative license made it legible and believable at architectural scale.

The finished piece replaced the earlier Moon in rotation, became a new flagship experience, and grew into a partnership with NASA around the Moon and future space-related opportunities.

Helping a new medium mature

The work was broader than any one tool.

I contributed insights and optimizations across the creative process: observing where momentum slowed, proposing practical changes, strengthening reviews, improving communication, and building lightweight systems only when they unlocked meaningful leverage.

Enabling the team

Tools that made creative decisions easier.

I built or helped deliver many production tools and workflows. ExosPreviewer and ExosMapper are two focused examples: earlier validation, less repetitive setup, and more room for creative judgment. Both have pending patent applications.

Preview

ExosPreviewer

Earlier validation of scale, framing, camera behavior, and multiple synchronized views.

Mapping

ExosMapper

Built to solve NHL Draft’s perspective-mapping challenge.

I built the tool that became ExosMapper to make mapping more flexible and reduce repetitive setup. It is now the subject of a pending patent application.

Creative direction in practice

The right visual idea mattered as much as the right tool.

Shared reviews connected creative, engineering, production, and operations. Concrete visual decisions gave those conversations a useful starting point.

Google Data

I helped develop kaleidoscope concepts to make a data center visually compelling. That exploration became the basis of the creative direction; I also led delivery and master compositing.

Celestial work

Each planet began with a scientific deep dive. I carried learning from earlier pieces forward while finding a different visual solution for the next world.

Creative contribution · Tool development

NHL Draft 2024 The perspective mapping needed for this production prompted me to build the tool that became ExosMapper. A specific delivery challenge became a reusable mapping capability, now the subject of a pending patent application.

What I carried forward

Creative quality rises when every discipline can see the same problem and learn from the same result.

The lasting contribution is a team that can carry creative intent through preview, review, mapping, and delivery with less reinvention.
