# Holiday Icicle Lights with Flair ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/085/547/medium800thumb/projects_ezgif-2-2d83bff3c93b.jpg?1575767510) I adore most anything with **LEDs** , but found those store-bought icicle or meteor lights a bit lacking. Nature rarely moves in straight lines and perfect intervals! In this project we’ll make our own, applying some basic physics for an eye-catching drip effect. PLUS…these have a built-in **magic trick** , making a “splat” where they hit the ground! This is a **remix** of an earlier project: the **[OOZE MASTER 3000](https://learn.adafruit.com/ooze-master-3000-neopixel-simulated-liquid-physics)** from Halloween…mostly it’s just **larger** now and uses different NeoPixel strips, and fits in a **window** rather than squeezing in a confined space. The code and principles are similar enough that you’d do well to skim that guide. Go ahead, I’ll wait here, then explain the differences when you get back… [Open OOZE MASTER 3000 guide in a new window](https://learn.adafruit.com/ooze-master-3000-neopixel-simulated-liquid-physics) The Halloween _Ooze Master 3000_ project was inspired by those unconvincing store-bought Christmas meteor lights, stepping it up with a bit of physics math to make the drips look “real.” Now we’ve gone full-circle and it’s a Christmas project again! The same installation can do double-duty…set up for Halloween with a blood or ectoplasm color scheme, then afterward just update the code for a Christmas-like mood. Unless you’re a horrible person like me… https://twitter.com/PaintYourDragon/status/1202828009813659648 - [Next Page](https://learn.adafruit.com/holiday-icicle-lights-with-flair/hardware.md) ## Featured Products ### Adafruit Feather RP2040 SCORPIO - 8 Channel NeoPixel Driver [Adafruit Feather RP2040 SCORPIO - 8 Channel NeoPixel Driver](https://www.adafruit.com/product/5650) If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs.
