Light simulation
Scientific simulation of light based on the idea of light as waves.
The circle in the center is an imitation of glass. Passing at a certain angle, the rays passing through the glass form a rainbow.
The calculation is slow, the first light sources will appear by the 20th-30th tick. For a faster calculation you can reduce the size, for a more accurate and beautiful result increase the size.
@bh , is it possible to add this to the science or maths collection?
