Kind of a weird video, but just wanted to share it since I thought it was pretty cool, prolly won't get many views :)))
Note: The blocks come in all dye colors and have luminous (best for greenscreens) and regular (best for building).
I did this by adding solid color blocks, then in my video editing program (Filmora 11), used the Chroma Key tool to turn some colors transparent. From there, I put stock videos/images (from Pexels via Filmora) on a layer that renderes behind it.
Music (Dolphi-esque - Godmode) from the YT Audio Library
