Here's a link to my simple Halloween display this year:

This is later in the night and some of the prop batteries had died. It is more of a 'haunted walk'. I have been using xLights to do simple animations (<1min) for almost all the major holidays as I have left the lights up all year, which isn't too noticeable as they are mostly strip. I have been on a fairly limited budget due to being unemployed but hopefully that will clear up soon.
I have been doing a Minecraft theme for about 3 years now. This year I put background sound effects in the sequence file that played over my stereo during the animations, and had a remote button press to trigger a scary monster sound effect (not working in video) and sequence where all the lights go crazy. It was fun for the kids. There were leds on the ground to simulate redstone dust. There were 3 mob heads on stakes (Enderman, Skeleton, Zombie box-masks) that I fitted with Esp8266s running Arduino sketches that ran led eye matrices and mp3 sound players with speakers, and changed mode upon activation of PIR sensors. The Ghast had a similar setup. The glowing lexan Creeper head had ITO plastic behind the face that detected touch and changed mode when touched. There was also a static Glowstone and Sword, and a Jack O'Lantern that was remotely controlled by EspPixelStick (not running in the video - battery died). I tried to make the front of the house look like a giant face using square eyes, and a squared off mouth made of EL Tape. Next year I'll probably do an animated mouth using xLights, but El Tape looks cool. I try to add a few more props each year but never seem to have the resources to do it all. I have a full size mobile robotic Creeper but couldn't get it working in time. I'd like to put the Ghast on a zip line and eventually add larger props such as a Portal, the Ender Dragon or Iron Golem and other robotic characters. Right now I'm about 50/50 with Arduino and XLights programming, but XLights keeps becoming more capable for this type of display so I hope to use more of it's features. Hope I can give some ideas to anyone interested in this kind of display.
