This remarkable mirror illusion came with a perfect unforeseen bonus

An optical illusion is good, but an optical illusion that’s also oddly amusing is better.

The latter is what graduate Luke Ritchie stumbled on in a corridor on his campus, when he noticed a perfectly aligned mirror.

And a happy coincidence at that – posted to Reddit, Luke’s picture has had thousands of upvotes.

“I suspect people find optical illusions fascinating because they enjoy seeing their minds be tricked,” said Luke.

“On Reddit I would hypothesise people enjoy them even more when they are everyday occurrences, interesting artefacts of our day-to-day lives.”
