That&#x27;s cute.  Now to make it a mass-produced product.  LED strips [1] are very similar; they&#x27;re long strips with LEDs and a simple ASIC in one package, wired end to end in long rolls. You plug power and a bitstream into one end and can control each LED independently. Cheap, and popular at Burning Man.  If someone can find a volume market for this, it should be easy to get it made.<p>[1] <a href="https:&#x2F;&#x2F;www.adafruit.com&#x2F;products&#x2F;1138?gclid=CMnogdfklssCFU9cfgodvhQJhQ" rel="nofollow">https:&#x2F;&#x2F;www.adafruit.com&#x2F;products&#x2F;1138?gclid=CMnogdfklssCFU9...</a>
