I wish I still had a slides projector and some old slides because..
When I was still a teensy tiny little girl my stepfather always made us watch his super boring vacation shots on the slide projector for hours without end. And of course for me to pass the time without falling asleep was to get ‘involved’ with the projections.
I remembered how childishly fun that was when I found some photos of me and my friends on vacation in Berlin. We went to an art exposition and on one particular floor was a dark room with images projected on every wall. Without other people there we played around with our shadows on the images and took photos of this.
I’m going to get a projector + slides somewhere secondhand and turn unknown people their slides into something new with shadows! :D
