Go fly a kite....

No, not the usual use of the term, but something I watched when in Singapore a couple of years ago.
While having a meal at Clarke Quay one evening my eye caught some strange lights in the night sky. I thought I was witnessing the arrival of some alien spaceships (helped by a few Tiger Beers) and eventually managed to make out they were some form of RC aircraft.
After our meal we wondered over the other side of the river and found that what I'd seen were actually RC kites - flown by a local club outside Riverside Point.

I may just pick one up to bring home when we visit in August...
