A tale of three generations

Two generations of farmers sit waiting for a plane. The father is wearing a traditional, shockingly pink turban while the son sports a "safari" suit of the sort favored by upwardly mobile rural Indians.

Meanwhile, just a couple of feet away, the granddaughter was experimenting with an interactive billboard. Advertisements were projected onto the floor from the ceiling and if the light-beam got intercepted, the image on the floor would show a reaction. For example, one ad about conserving water would show ripples around the place where the girl was standing and the ripples would follow her as she twirled on the floor. Another ad, for checking accounts, had coins that magically rearranged themselves as she walked around. She was curious about how it worked and was trying out different positions so as to understand the pattern.

The story of India in microcosm.
