A grandmother in Valencia, Spain, is going viral for her intricate drawings of nature and landscapes. Each one is hand-painted, but not necessarily in the way you'd expect.

Concha García Zaera creates her digital masterpieces using Microsoft Paint, often spending two weeks or longer on a single drawing. According to UltimaHora, the 87-year-old runs the graphics editing program on Windows 7 and uses a mouse to perfect her paintings — many of which are inspired by postcards her husband used to send her.

Indeed, her artwork shows an incredible attention to detail: Waves crash on a shore; blades of grass blow in the wind; light and shadows add movement and depth. 

A longtime art enthusiast, Zaera told Radio Valencia that she used to channel her creativity into oil painting classes. But the strong smell of the oil paints prevented her from practicing at home, and she eventually had to stop. Luckily, after her children gave her a computer, the grandmother realized she could keep drawing using Microsoft Paint.

That was around 12 years ago, around the time her husband fell ill, Zaera said in an interview with El Mundo. "I had to take care of him, so I couldn't go out very often," the grandmother explained, as translated by BuzzFeed. "I began painting little things: First, a house. The next day, I'd add a mountain. [...] Step by step, I was adding details, and in the end, the result was a very pretty thing."

Until recently, Zaera shared her artwork with a limited audience on Facebook. According to Vanguardia, she didn't make the switch to Instagram until one of her granddaughters suggested it. When her paintings started going viral earlier this month — after Twitter user femilimon posted a screenshot of her account on March 9 — she only had 361 followers.

Now, less than two weeks later, the grandmother has over 124,000 followers on Instagram and counting.

Despite her newfound fame, Zaera has remained humble about her talent. "I do not understand very well why my drawings draw so much attention," she told Vanguardia. "I think they are very simple things."
