FROM A BRIEF TO A WORKING EXPERIENCE

Choose a starting point that fits your project.

A new experience: bring the brief, intended audience and creative direction. Explore Design.

An existing installation: assess the peripherals worth retaining, retrofit the playback and control foundation with QuickSilver, then consider the AV++ capabilities it can support. Explore the retrofit sequence.

A technical integration: define the interfaces, current capability, operating limits and verification needed. Discuss an engineering requirement.

The family below includes established tools, implemented components, working demonstrations and continuing development. The chosen project scope identifies which apply.

PURPOSE FIRST. A CONNECTED FAMILY.

One purpose. The capabilities to keep delivering it.

Mad Intelligence™

Patent pending

The designer sets the purpose. Mad Intelligence keeps it active.

Mad Intelligence is the overarching layer for purpose and continuing engineering. It brings the intended experience, the capabilities that can realize it and the evidence of the result into the same operating picture. The aim stays active through everyday operation, changing conditions and future upgrades.

Governed operating architecture

Patent pending

WorldModel™

The WorldModel™ architecture defines governance, consent, multi-system coordination, safety intervention and accountability for intelligent physical environments. Shared operational state supplies context within that wider design; it is not the complete architecture.

Realization and technology family

AV++®

AV++ brings together the technologies that make the experience happen: media, sound, personal storytelling, language, access, show control and operator tools. QuickSilver® provides the distributed computing foundation.

Mad Hatter™

A DSP with a much wider role. Hatter brings its processing foundation together with soundscape authoring, spatial listening, listener context and acoustic evidence. Mad Intelligence connects that acoustic work to the purpose of the whole experience.

SPECIFY THE EXPERIENCE

Bring the needs together before choosing the parts.

A capability list becomes an installation through design and engineering. We assess the site, audiences, content, accessibility requirements, network, operating responsibilities and the physical results that must be achieved.

Some technologies are established delivery tools; others are developing capabilities or published architecture. The individual pages explain that scope. The project specification and commissioning evidence establish what is included and demonstrated at your venue.

Our IP register distinguishes issued patents, registered marks and pending work. You can also explore the published architecture or arrange a focused visit to Wonderland.

Why Are We Doing This?

Five monkeys parable illustration

Five New Monkeys

There is a well-known parable about five monkeys. It is not really about monkeys. It is about what happens when a group keeps enforcing a rule long after the original reason for that rule has disappeared. In AV and Location Based Entertainment, that pattern shows up all the time.

Five monkeys are placed in a habitat with a ladder in the middle. At the top of the ladder hangs a bunch of bananas. Naturally, one of the monkeys climbs the ladder to grab the bananas. When it does, the researchers spray the rest of the monkeys with cold water. After a few attempts, the monkeys quickly learn the connection.

Banana = Cold Shower.

Before long, whenever a monkey even tries to climb the ladder, the other monkeys pull it down and beat it up to stop it.

  1. One original monkey is replaced. The new monkey tries to climb. The others attack. It learns not to climb - even though it has never been sprayed.
  2. Another original is replaced. Same result. The new monkey learns the rule.
  3. This continues until all five originals are gone.

None of them have ever been sprayed. None of them know why.

But none of them will climb the ladder. And if a new monkey tries, the group will still beat it up.

Why?
Because that is just the way things are done.

That is how large parts of this industry still operate.

Too many teams inherit technical assumptions from the last project, then production assumptions from the last technical stack, then budget assumptions from the last production model. Eventually those assumptions stop looking like choices and start being treated like physics.

Much of that behavior comes from designing around proprietary black box hardware. Once a system is built on closed, single-purpose devices, everything downstream begins to conform to their limitations. Workflows. Support models. Spare strategies. Upgrade paths. Before long, entire organizations are protecting the ladder - without asking whether the ladder still needs to be there.

We chose a different starting point.

We built a system that bases AV hardware on non-proprietary compute node hardware rather than on closed black box endpoints. That decision changed the problem space.

  • Hyper-personalization became possible - behavior no longer had to be locked inside fixed-function hardware. Experiences could become adaptive, contextual, and individualized in software.
  • Spares were minimized - standardized around a smaller family of node types instead of a growing inventory of specialized proprietary devices.
  • Upgrades became easier - increasing capability often means increasing compute available to a node, not replacing entire subsystems.

We did not set out to defend the old ladder. We set out to remove the reasons people thought they could not climb it.
