These are called sunflecks, which form on the forest floor during partial solar eclipse. The openings in the forest canopy act as pin hole camera producing these kinds of beautiful patterns.
Here is another image of the same phenomena on India Nature Watch - http://indianaturewatch.net/displayimage.php?id=131671
I was also unaware of this phenomena until MB Krishna on Bngbirds (a yahoo group for birding and nature related discussion) explained it briefly over the forum. Below are his words -


In dense tall forests the spots of light which reach the ground, called
sunflecks, are very important. They give the much needed light to the understory
plants, in a light deprived forest interior, to carry on their photosynthesis.
Some forest interior plants are especially adapted to capture these passing
spots of light.

Today, during the eclipse, one could see all these light spots becoming cresent
shaped, because the gaps in the tree canopy all acted as a multitude of pin
holes (as in a pin-hole camera).

Under trees with fine leaflets, the pattern formed was quite intricate, with the
pattern of the pinnately compound leaves adding to the shape of the eclipsed
Sun.

In good faith,
krishna mb.
