Hi there,
Here is the KIT addition dual Strips…code
and the Ring, a.k.a. SUN 
// =============== Dual NeoPixel Test (Balanced, Sequential) ==================
// ESP32-S3 (BSP 2.0.17)
// Strip A: GPIO 38, 8px
// Strip B: GPIO 2, 8px
// Self-test: Strip A then Strip B, each pixel R->G->B (1s each)
// Patterns (low-stress): For each color, run KITT on A (B off), then KITT on B (A off),
// then Barber on A (B off), then Barber on B (A off), repeat through color list.
