3D arrow optical illusion leaves Twittersphere scratching their heads
‘What kind of sorcery is this,' said one Twitter user after seeing an optical illusion which has left many, including Thandolwethu, baffled.
Since it's a short week for some of us, it's the perfect time to challenge your brain - and I've got the perfect optical illusion for you.
The illusion was created by Japanese mathematician and sculptor Kokichi Sugihara. It shows a 3D arrow on a stand pointing to the right, and no matter how many times it's rotated, it will always turn right.

A video of the illusion was shared by art director Tham Khai Meng.
"This arrow by mathematician and sculptor Kokichi Sugihara can’t point left,” he tweeted before disclosing the trick behind the illusion. “Here’s how it works: It’s 3D-printed with a bunch of curves our brains don’t register,” Meng tweeted.

Okay, so I've legit watched the video over and over again. My brain hurts and I've even turned my screen around and nothing makes sense. Strange.

Aaahhhh! I'm so frustrated right now.

The fun kind of frustrated though so
I'll be fine. If I watch it enough times
I'll be able to see it correctly, right?😸💕💕💕😸
There's little doubt it's to do with the lighting, design and cam angles. The brain just can't "read" it.

I turned my computer upside down and the arrow pointed left. This means it's probably the camera-angle causing an optical illusion, like those trompe l'oeil sidewalk art pieces. When you're not in the sweet spot, they don't look right.

The video looks cool, though.
