## What it is
Scenic is a client application UI framework for Elixir/Erlang/OTP that renders 2D retained-mode interfaces directly on top of OpenGL. It targets fixed-screen connected IoT devices (especially via Nerves) while also supporting portable desktop applications across macOS, Ubuntu, and embedded Linux.

## Use cases
- build a UI for an embedded IoT device with a fixed screen
- create a kiosk or appliance interface in Elixir
- write a portable 2D desktop application without a browser or JavaScript
- run a fault-tolerant self-healing device UI on Nerves/Linux
- package reusable UI controls as Hex packages
- remotely access and control a device's interface over a low-bandwidth connection

## When to choose
- you are building Elixir/OTP applications for fixed-screen IoT or embedded devices
- you want a small dependency footprint (just OTP and OpenGL) with no browser or JavaScript
- you need fault-tolerant, self-healing UIs backed by OTP supervision trees
- you prefer retained-mode 2D graphics with game-style transform matrices

## When to avoid
- you need HTML, CSS, or web-based rendering
- you need 3D graphics
- you prefer immediate-mode rendering
- your team does not work in Elixir/Erlang
