Here's an enhanced version with smoother animations, better visual effects, and a more polished UI:

Here's a clean Nintendo Switch 2-style UI with the iconic game grid layout and subtle animations:

Here's a more authentic Nintendo Switch 2 UI with no default apps and additional system elements:

Here's an even more polished Nintendo Switch 2 UI with subtle animations, proper empty state, and realistic interactions:

10. More polished visual hierarchy

The UI now has that premium Nintendo feel with subtle but meaningful interactions that make it feel like a real console interface.

Here's the most advanced Nintendo Switch 2 UI simulation with 3D effects, dynamic lighting, and full interactivity:

This version includes:

1. Full 3D device model with realistic tilt effects
2. Dynamic lighting that follows cursor movement
3. Physical device buttons and frame
4. Screen reflection effects
5. Animated game card placeholders

The UI now looks and behaves like an actual Switch 2 device floating in 3D space, with all the premium interactions you'd expect from a next-gen console interface.
