Building games & AR/VR experiences from Patagonia.

I'm Gonzalo Zeiss, a game developer and computer technician. I ship video games, augmented and virtual reality applications. Mostly in Unity and C#, sometimes in Unreal and C++. I care about interactive experiences that connect with people, and I keep exploring new tools and engines.

3D monuments at your fingertips

Point your phone at ruins like the Colosseum or the Roman Forum and watch them rebuild in 3D. Temples, statues and gladiator arenas rise from the rubble.

Epic storytelling

A virtual narrator guides you through tales of power, betrayal and daily life in ancient Rome. Choose your language: English, Italian or Spanish.

Cardboard lens immersion

Pop your phone into a Cardboard lens for 360° immersion. Or keep it simple: handheld AR works anywhere, anytime.

Ready to experience Ancient Rome like never before? Download RARO, put on your headset, and begin your journey through time.

Developed with archaeologists and 3D designers for historical accuracy.

Virtual production & ICVFX, end to end.

A rare cross-skill on the market: real-time engines (Unreal, Unity) plus live show technology (GrandMA3, Resolume, Madrix). The exact intersection that LED-wall sets, immersive installations and stage productions need, but few people cover at once.
