A page of the Crazy Optical Illusions: Artbook. An elephant with an indeterminable number of legs is printed large on the paper. Text to the left says, top to bottom, 'Roger Shepard's Shepard Elephant', 'How many legs does the elephant have?', and 'Posted on the 17th of April, 2020'.

We do not post 'ragebait'. If you truly do not understand one of our illusions, please reply so we can help you or put you in our book. Thank you. 𓃰

A render of a book page, featuring replies from confused or mischievous social media users.

From top to bottom: a user replies 'iont get it', with a screenshot of the quoted 'Endless Staircase' illusion. Another user replies with 'what are you talking about about its an endless staircase'. The original replier says '?'. Another user replies 'why cant i remember my childrens names'.

A separate reply says, 'This isnt the endless staircase. None of your tweets are actual optical illusions, are you taking the piss?'.

Another reply says, 'Who cares its a drawing'.

To break character - in 2022, Roger Shepard, pioneering cognitive scientist and creator of many famous illusions, passed away from Parkinson's. We use a version of his Shepard Elephant as a mascot. In honour of Roger, 10% of profits from our artbook will go to USA + UK Parkinson’s charities. ♡ 𓃰

How many legs does the elephant have? At first glance, the answer maybe be obvious - but look a little closer, and this fiendish illusion reveals itself. (HD reupload)

Which way does the staircase go? In this famous 'Endless Staircase' optical illusion, it's impossible to tell if the stairs are ascending or descending, leaving the observer thoroughly perplexed.
