The image above is of a sun dial. The large middle piece casts a shadow on the curved section to the right. It is accurate to within two seconds of modern verification. The image below looks like a sculpture garden but is 12 separate stations, each devoted to tracking a sign of the zodiac for important astrological purposes.
On my last day in Jaipur I went looking for turbans and kites, turbans because they are colorful and vary by tribe and region (which took visits to several shops), and kites because flying and completion is important all over the region (e.g. The Kite Runner) and I liked the looks of them. The string is made of glass, the better to cut loose a competitor. Kites begin at four cents apiece, then ten, then a whopping 30 cents. I bought about 35 for $1.80. A half mile of string is a dollar. Kite season is later in the winter.
