Hi Shelby & Brent!
Naw... it's a Virtual Background System. I simply switch off the lights and let the lamp reflect the background only off the screen.... way too simple:) We used to call it a "Front Projection Screen" or a "Environmental Background System". Same improved process... different name:) - Albert
Whooogh! You really must know something about lighting. I just look at the incredible shifts of rich color with admiration. The one I cannot figure out is the yellow light bottom right. It looks like the foreground "O" then the lady then the background - given that I cannot figure out how I would position the light to get the shadows you did.
Pretty dang cool. I really like silohettes as a graphic design element. This is got to be one of the most unique!
