Or use a projector type light like a stage Leko or Source 4 or Dedolight with a lens projector attachment, with gobo patterns that can in inserted into the light.

Im trying to make interesting shapes ( random, vertical, horizontal, window shapes, etc) appear in light behind subject on the background wall surface. I have black 20x30 foamboard, assorted worklights and different lamps to screw into them. I cant seem to make a clean light pattern on the wall with the shapes that I cut out. Can someone tell me what type of "guerilla" lights to use, size that cut outs should be on 20x30 foamboard to make decent believabel window shapes, angles, and also the distances (ie; how far back the pattern is away from the background wall to be lit, and how far the light source should be away from the pattern) I'm stuck!!!!!! so far I have tried a halogen spot/flood par20 50w in a aluminum clamp light and the spill from that worked better that the actual beam did. Have also tried assorted household lights. Tried all at different distances and angles and still frustration.
Following up David?s good advice, I?m assuming that by ?guerilla? lighting, you may not have access to professional instruments. David?s referenced projector light because it?s a very linear, focusable source, with little spill. You get a cleaner confined beam, hence, sharper shadows. Find an old slide projector or filmstrip projector to use as a light source.
