I have used the prism visual metaphor a few times in my client's presentations to show how rich, intricate, subtle components are present in a service or product that might not be apparent from the outside. Below is an attempt at a minimalist pyramid in PowerPoint (roughly modelled based on the cover of that Pink Floyd album).

I simplified the laws of physics here and there, the tricky bit was to get the blue shape inside the triangle right. I added the slide to the template store yesterday, you can find it ready for download here, and subscribers can do so free of charge.
