Open-source VR desktop experiment
Your screen. In VR.
Turn an iPhone and a cardboard viewer into a wired virtual display. No expensive headset. No cloud. Just USB and an unreasonable amount of curiosity.

The pitch
A virtual monitor should not require another mortgage. NerdLens explores the scrappy version: hardware you already have, a cable you already own, and a stack you can take apart.
Under the hood
One screen.
Four hops.
The whole system is deliberately legible. Capture it, compress it, tunnel it, render it. No black-box streaming service in the middle.
Compress
Frames become straightforward JPEG payloads in the Tauri host.

Tunnel
A tiny TCP protocol rides a local USB tunnel to the phone.

Render
Unity paints each frame onto a display inside Cardboard VR.

Your viewport,
your rules.
Preview the stream, watch the connection, choose a target frame rate, and push the display deeper into your virtual space—all from the desktop host.

NerdLens is a proof of concept, so setup is still a hands-on affair. Bring an iPhone, Google Cardboard, Unity 6, and a Mac with Xcode.

Strap in.
Ship pixels.
NerdLens is early, open, and asking to be made delightfully overengineered.
