Concept Highlights 

Simmetri, our engine and playful creation tool, is already out in the wild, being used by interactive-design artists to create XR experiences. With our tool, artists use VR trackers, networked devices, MIDI controllers, and many other inputs to drive interactive 3D experiences without having to wrangle a development environment, juggle versions, or Frankenstein together SDKs.


With Magic Leap's partnership and resource support we plan to adapt our engine to work seamlessly on and with Magic Leap. The marriage of Simmetri's celebrated intuitive user-interface and graduated learning curve with Magic Leap's unparalleled hardware will form a seamless, spatial-and-desktop synchronous creation experience we call "Magic Creator Express." 

Magic Creator Express is:

  • an out-of-the-box, Magic-Leap-specific engine and creative studio that works synchronously across headset and app on computer.  It enables: ​​

    • out of the box cross-reality creation, synchronizing spatial and screen-based creation;

      • creators to experience instantaneous scene changes and code edits in headset and visa versa. 

    • creation with the best of spatial (positioning/world-building, immersive animation and testing) and the best of screen (scripting, meta-level organization, property-tuning).  

    • plug-and-play MR tool-sets: like context-reactive / procedural logic tools: leveraging Magic Leap's computer vision and semantic scene description API.​​ ​

    • if we can say it... Project MARS meets WIX

Magic Creator Express will:​​

  • unlock a missing-middle; millions of under(or over)-equipped content creators:

    • those wanting more unique expressiveness than quirky sandboxes (e.g. Anyland, MindShow) or singular creative components (e.g. TiltBrush, Tivori) and yet less-cumbersome workflows and more turn-key tools than current game engines (e.g. Unity and it's multitudinous variably-versioned SDKs). ​

  • integrate connectivity across the Magic Leap device, webAPIs, and PC hardware inputs to enable deeper mixed reality experiences: 

    • Think... projection mapping + Magic Leap applications. Think.. Magic-Leap + Ableton or Touch Designer  

  • enable instantaneous app/experience publishing. Create on Magic Leap, publish on Magic Leap.​​

  • roll-out UX-managed tool-sets at the speed of Magic Leap feature development

  • leverage Simmetri's celebrated interactive tutorial system for a creative and fun learning experience.​

User Reviews 

Early Release goals achieved: User delight.  Product distinction.  Repeat Use.


“WOW. Simmetri is probably the best money I've ever spent on an app. It's ridiculously affordable for what it does. On top of that, it's VERY well-coded, the interface is very snappy, engine is REALLY fast.'s easily way more intuitive and polished than just about any other 3D or Game-type engine tool I've used. You can tell the developers really know what they're doing.“

I'm a professor in the creative writing program of a large public university. I've long been on the hunt for a tool that would allow me and my students--almost none of us STEM types or coders--to make narrative art in VR (and in 2D). Simmetri is that tool.”


“Simmetri interactive tutorials are probably the best i've ever walked through! Fun, nicely constructed and well-rounded for quick intro. Hundreds of time i've heard word ''gamification", first time i see somebody have properly implemented it in software learning curve.”


The Team

We’ve been working together as a team for the last 2 years. We see ourselves as the dark horse mixed-reality engine you haven’t heard of yet. We came out of hiding this year, Early Releasing the Simmetri engine/creator studio on the Steam marketplace. We’re passionately dedicated to mixed reality creativity. We see a vast gap in content creation tools for the ‘everybody else’- those who don’t have a CS degree, those who are not game-developers by trade, those who haven’t dedicated two years of their life to debugging their way through a Unity deployment. We’re highly focused on accessible, turnkey, delightful user interfaces for MR experience design.

experiences. Amedeo has been designing and writing applications since 1993; most of the time focused on writing native C++ graphics and audio engines and the creative front-ends built on top of the engines. He’s been working on Simmetri full time for over 10 years. In 2014 he added in support for VR. Before working on Simmetri, Mapelli was one of the original founders of iZotope, a leading audio software company for the music industry, serving artists such as Trent Reznor, Nine-Inch Nails and Jay Z.
