Water-logging on the rooftop has caused growth of algae which in turn gets infected by rust also. The brilliant chocolate brown and reddish color of algae patterns is acquired by rust and dust stocked there. Surprisingly, the patterns first grow into an unique floral design which developing into large flakes looks similar to a speedy horse overall. The resemblance of algae patterns with a running horse is a rare event manifested in the nature -- certainly looking fabulous and mind-blowing!
