what do people make with this?

VIBE 1

Render hundreds of UI elements like buttons, sliders, and waveforms at 60-120fps in an interactive app.

VIBE 2

Replace a CPU-heavy graphics library that's causing frame-rate drops in a real-time iOS or macOS app.

VIBE 3

Draw shapes filled with solid colors, gradients, or textures without manual tessellation.

VIBE 4

Build a high-performance music production or creative app UI on Apple devices.
