Unusual but true: Optical illusions on the crosswalk

In unusual but true stories this week, we have UK's first "3D" crosswalk, the world's only "hypno-dog", artwork painted with coffee, a pancake race and a woman marrying her boyfriend after rejecting his proposals for 43 years.

Odd and interesting anecdotes from around the world are here in our review.

UK's first '3D' crosswalk

The first "3D" crosswalk in the UK was painted in St John's Wood, London, in a bid to slow down the traffic, BBC reported.

The optical illusion, which creates a floating effect, was introduced in St John's Wood by Westminster City Council as part of a 12-month trial.
