"It looks very bright when the dark image is changed to the bright one."
"Did this mirage help sink the Titanic? The optical phenomenon called Fata Morgana can make strange shapes or a false wall of water appear above a watery horizon. When conditions are right, light reflecting off of cold water will be bent by an unusual layer of warm air above to arrive at the observer from several different angles.
One hundred years ago... such a Fata Morgana mirage might have obscured real icebergs from the clear view of crew onboard the Titanic. Additional evidence for this distortion hypothesis arises from the nearby vessel SS Californian which reported sightings consistent with Fata Morgana mirages. The above Fata Morgana mirage was taken off the US Pacific coast in 2008."

What to see :
Below you see a rotating array of blue crosses and 3 yellow dots. Now fixate on the centre (watch the flashing green spot). Note that the yellow spots disappear once in a while: singly, in pairs or all three simultaneously. In reality, the 3 yellow spots are continuously present, honest!
What to do :
You can use the slower/faster buttons to change speed. Disappearance persists down to surprisingly low speeds. [If there are no buttons on the right, please update your Flash player.]
You can use the larger/smaller buttons to change size. Disappearance persists up to surprisingly large sizes.
You can use the “back-col” button to change the background colour. The yellow dots disappear into whatever colour the background has.
The ‘defaults’ button at the top restores the standard settings.
