Pixel art decoration
People with refined imagery often go for strange and abstract thoughts for their living room walls. Some paint them haphazardly; others make them nude or paint it in texture. Some have them laced with a giant portrait. Pixel art decoration has also gained sway in certain circles.
You may do it with the help of Plaster of Paris or intricate woven designs. That will however need a mixture of color and weaves. Pixel art perhaps comes out best on plywood. You may dip it in ink and then paint your imagery with acrylic. Make it in small squares to resemble pixels. To get the best understanding of pixels, think the dots to hide an obscene scene in television movie.
You may opt for easy art like farms or birds. You may even go for entire themes. The ultimate outlook depends on expertise of artist. You can and should hire professionals for best effects.
