Ten years ago, 98-year-old Hal Lasko began to lose his eyesight and feared his days of oil painting were over.
But the legally blind artist has been given a new lease of life - thanks to the outdated computer program Microsoft Paint.
The great-great grandad, known as the 'Pixel Painter', may not have kept up with the smartphone revolution, but is still a master with the 1990s pixelated art software.
His grandchildren gave him Microsoft Paint fifteen years ago, but soon after he contracted wet macular degeneration - a condition which blurred his central vision and made colours appear washed out.
Hal, a retired typographer from Ohio in America, worried he would not be able to keep up with his painting hobby and started to use the basic computer program more.
Now the artist, who has lived through two world wars, uses digital paintbrushes and pencils to create his Microsoft masterpieces - which are far from amateur.
Hal said: "The first piece took six months. Now they can take anything between four and 30 days.
"I do a lot of my painting with my eyes shut. When I lost my eyesight I thought my painting days were over. I'm using the computer because it gives me the benefit of magnifying enough so I can still do it.
"If it takes me to two years to do something, I do it. I jump out of bed to get to the computer every morning to do what I dreamed I could do.
"When I worked I always had to please the client, now I can do whatever I want."
Hal, who has three children, 10 grandchildren, eight great-grandchildren, and three great-great grandchildren, doesn't use computers for anything else.
He spends ten hours a day on Microsoft Paint, and has so far completed 150 paintings.
Son Ron Lasko said: "Sometimes he talks about it in his sleep. He will talk to you about light for as long as you want to listen."
