Many of us fear, or are at least a little wary, of the unknown. And when your doctor prescribes magnetic resonance imaging—better known as an MRI—to check in on the inner workings of your body, there is a lot of unknown!

As the chief technologist on a 3-Tesla research-only MRI machine, Andy Ellison knows the inner workings of the MRI machine better than most. Recently, he took to using fruits and vegetables for quality assurance, warming up and testing the machine, before using the MRI scanner in his research-only lab.

And the results of his experiment are surprisingly gorgeous.

Speaking to Salon about when he first tried placing orange slices in the machine, Ellison says he was “blown away by the incredible complexity that began to show itself so quickly.” With a bit of artistic discretion, he began to link the images together, creating a kind of animation.

The result? The orange appears to bloom, right before your eyes. And soon, he began experimenting with other fruits and vegetables, like this pineapple:

Ellison’s Instagram account, aptly named @inside.insides, sheds light on an array of other, gorgeous fruit and vegetable animations. The star fruit glistens and grows, looking like a Disney character from an underwater cartoon. And the lowly onion transforms into a rock falling into calm water, bringing ripple after ripple through the dark:

Brussels sprouts—boring green balls by day—become eclectic and alive, spinning into view and back out again. Even pea pods become like cave drawings, stretching out against the black:

“Ultimately, I think people like to look at common things in a new light,” Ellison tells Nerdist.

Human beings, of course, are anything but “common.” But the next time your doctor prescribes an MRI, perhaps spend the 30 or 60 minutes imagining the beautiful images being created from your head, heart, or spine. As the saying goes, true beauty comes from within!
