I have a thick piece of red plastic which I found on the road and is probably part of a car light. Husbandy drilled a hole through it for me and I can just hold it over the lens and direct where to aim the hole.
This is just a white corrugated wall with a lovely shaped shadow laying across the wall. The red plastic has made the red wall and the hole has accentuated a part of the shadow, simple and effective and good fun! :o)
