Here i have used a black light as i know in some night clubs there are black lights. But it does not produce the room lighting quality, doesn't create shadow well and you cannot see the clear acrylic well.

 The light being used is a direct spot light which highlights the acrylic but is too powerful for shadows.

 This is using two light sources again but spread out further which lights up the space whilst creating shadow.

 The light is directly above the piece to see how the light would pass threw the acrylic and highlight each line.
