Last year, when this cool dad posted a short video of his daughter sporting an LED Halloween costume, the video went viral - to the tune of over 22 million views. This year, "Glowy Zoey" has been updated - and it's cooler than ever.

It has 12 modes and 372 LEDs (124 chips with 3 each)."

I'm not sure what any of that means - so here's a video tutorial on how to DIY:
