My project has changed a little bit and I don’t need to cast shadows out of a center point any more. I did do some more research for anyone else that needs to cast large shadows.
I got a Fresnel lense from @SDY and decided to try it out.
It didn’t work to great straighten out the light.
I have been told that I should actually use a single point halogen light instead. Thats what is used in this project http://www.cubebreaker.com/laser-cut-cube-shadow-art/
I didn’t get a chance to try out any of the other ideas in this thread. Thank for your advice everyone.
