A demonstration of shockwave 3D's abilities.
There are two wave point sources. One is fixed at the lower left,
and one moveable initially at the lower right. Initially far apart,
the interference of the two waves is turbulent. As you adjust
the position of the moveable source closer to the fixed source
the interference begins to spread, taking on those qualities we
associate with double-slit interference patterns. Alternating light
and dark bands (wavey and flat areas) are very apparent.
