Can you read the phrase above?
It is presented backwards as well as upside down.
A few years back there was a meme about an university research study showing how misspelled words and scrambled word order don't impinge reading comprehension. Well, the example above falls along those lines. Sadly, the research regarding the university study seems to be an urban myth .
BUT the mind DOES have a fantastic way of taking indistinct stimuli and morphing them into something that makes sense to us. Whatever the reason this word-order-thingy occurs, research based or not, it's totally cool.
Here's an upside down/backward writing generator for you to enjoy.
