Hi Stefan.
Impressive results.
Maybe you could elaborate what is going on?

Part of white light beam reflects, part refracts
Refracted light again reflects and refracts, to rainbow, etc.
How is the rainbow of colors achieved. Does the color spectrum reflect physics and reality? (Within the limits of rgb colors?)

Is the prism flat on all sides, or concave?
So MoI made the prism?
