Isn’t this cool. After seeing someone who made a letter in shadows I wanted to see if I could do the same with a heart.
I first worked it out with my 3d modelling software to refine the shape before cutting it out.
The base is plywood to hold it all in place, while the shape is blackcardboard.
Holding up to the sun in the right orientation the shadow is cast to make the heart appear!
This opens up so much more that could be done with architecture and sclupture by just playing around with the height of things and how that shape edits the shadows they cast.
