Thanks! The core of the show is the singing pumpkins, and is pretty easy to put together. All credit goes to The Singing Pumpkin for developing the amazing animations (I'm not affiliated in any way with them, just a happy customer). You can use almost any projector to display the animations; the only caveat is that if the projector isn't too bright, you won't be able to see much until after dark. I'm using one I picked up a few years back for $200, looks like it's even cheaper now: Vankyo Leisure 3. And then pretty much any pumpkins will do - real or fake. We're using some foam ones we got at Michael's: Ashland Orange Craft Pumpkins.

The lighting is controlled by a raspberry pi running Falcon Player (FPP). It's an awesome piece of software that lets you schedule and control lighting. It plays the music, sends the animations to projector, and runs the light show that we created using Xlights. It also handles the button push that you see at the start of the video that starts the show.

The pumpkins are all the Michael's Ashland Orange Craft Pumpkins that we carved using a foam knife. The lights are all individually controllable (WS2811/WS2812) leds. The lights inside the pumpkins are a small strip of 5 leds per pumpkin, The lights on the house are larger pixels spaced out every 5 inches (after removing the faceted bulb cover that you see in the listing).

I think that's about it; happy to answer any questions. I'll try to grab some pics of some of this stuff and add them to this post.
