thanks @iseekbeauty , @aussietony , @charlie61074 : I can't do these anymore because I sold my slide projector (down sizing my living space). It was always fun to make this type of photo.
Fantastic! LOVE this ! Absolutely Wonderful concept! :-) Such a simple technique, yet Beautiful in its execution! Actually reminds me of the stage effects used by The Pink Floyd, The Who and other start-up bands of the early 1960s :-)
