It's no day at the beach, even though there's aquatic life everywhere you look.
"I thought it was pretty cool actually," says Roanoke Catholic senior Alex Wall.
Senior Laurie George agrees, "I thought it was really unique, I didn't think it would look as detailed as it does."
Not bad, considering just about everything here is made of yarn.
"The beauty of this is that it is really inherent. The yarn and crocheting really works well with the shapes and the colors," explains Gallery Director Talia Logan.
The Hyperbolic Crocheted Coral Reef is a national idea that got local attention after math teacher Jan Minton saw it online.
Explains Minton, "In plane geometry, a plane is flat like a table top. But in hyperbolic geometry a plane is quite "ruffly" and that was the inspiration for the connection between the math and the coral reef."
About 250-people, from ages 4 to 90, started off with a lil bit of yarn. When it was all said and done, that yarn, was transformed to look like this.
Most of the exhibits are of "healthy" reefs with vibrant colors and active animal life, but there are others.
Like, a "bleached" reef, done in whites and creams; pretty, but an indicator the reef is dying.
And, a "toxic" reef drawing attention to trash in the ocean.
The exhibit features solo cups, chip bags and even an octopus crocheted of Walmart bags.
The exhibit ends on Monday, March 3rd.
