Shadows Play

There should have been 3 or 4 pillars, and string connecting consecutive pillars towards the pillar bottoms. Over this string, shadows moves like as if on a rail. Its like a shadow play using 3 windows.

I am just able to make out the shadow of a horse, a camel and an elephant while it slides from first pillar to next.

And while it slides in the next window (between the next 2 pillars) these 3 shadows are out of focus and zoomed in so big that I cannot make out the figures.

But while they slide slowly in the last window the figures are very clear and sharp.
