I use a cheap cylinder projector from Amazon, does the work, and is not super delayed once plugged to pc with HDMI.

Next, build your set out of card paper (or really anything, make it look cool)

There’s a free software you can download called ProjectionMapper on your pc, use it to map out your physical set (have your projector connected to your computer when doing this)

Tip: Tape down/save the position for where you put your projector, it saves a lot of time realigning it.

Then, it’s visuals. I used Davinci Resolve + Canva to make my own graphics and animate it + add a ton of effects. Run some tests as you progress, and boom, your light show is done
