The big ferris wheel in Melbourne (the Melbourne Star) against the afternoon sun. This was taken soon after it opened for the first time, when it was still called the Southern Star - it stayed open for only a bit over a month, then it had to be taken down due to structural damage, and it wouldn't open again until five years later.
