|Deceptive Red Ray
A red ray appears to beam straight up from the Eureka Tower Melbourne, Australia.
Ash Crill took the image from St Kilda Pier at sunset on 1st February '13.

|Part of the facing side of the Eureka Tower inclines inwards. Its windows act as a giant, slightly tilted, mirror.
The 'mirror' reflects the near horizontal and reddened rays from the setting sun into a narrow beam that points backwards and crosses the river towards the camera. The beam slopes gently upwards. To the eye or camera it looks as though it points vertically from the building - that is an illusion.
