Using projectors in photography has been done for years and it’s something that we can very easily implement in 3-D. Photographers use projectors in their work because it adds this kind of sci fi look to their work. The concept here is similar to gobos but in this case you can make animated content for that to truly look like a projector would be needed to make this work.
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
