While looking for ways to spice up my formal wear, I came up with the idea of hiding some NeoPixels in a pocket square. The front pocket is great for a number of reasons:
1.) Lots of space to hide a large battery.
2.) White pocket squares (the only kind in my book) make a great diffusion
3.) Pocket squares are often folded in a rectangular fashion. Many gents use
an index card, so a strip of NeoPixels work just as well.
This project could actually be a great gentleman version of the chameleon scarf.
