eleusis

Hi Swansont. So basically a very bright white laser?

I really hope you don't mind me asking questions here as Im not a science head. Instead im a craftsman. Normally Google is my best friend when if comes to finding out stuff but im stumped here to get the right help. Basically I make suncatchers using crystals. . combinations of faceted spheres and octagons. For display purposes I want to be able to refract them on a wall using artificial light. Iv tried this with no success. Does it need to be a super strong bulb held close or far?or is there a type of light or bulb that I should be using to achieve good results? Hope someone can help Thanks in advance Dave
