Pixel art is mostly known as a form of digital art which is
done by using raster graphics software, where the images created lose quality
when they are resized. A digital image is made out of millions of pixels, which
are normally represented by dots or squares and are not visible in high quality
images, but in pixel art all the pixels are purposely shown as if you were
zooming in on a raster image. Although pixel art is more associated with
digital art, some visual artists have found a way to recreate pixel-like art in
real life, such as mosaics and beadwork.
Pixel art was initially used in old computers and consoles
due to the small screen resolutions and low-powered hardware at the time. The characters
and objects in the games were not so visually complex and they had a restricted
color palette. With that said, many developers focused on having vibrant colors
for the characters in the game in order to make them stand out from the
background, like the Sonic the Hedgehog video game franchise, which was
developed by Sega and released in 1991. The game mostly focuses to convey the
speed and power of the console, and is not really associated with pixel art
gaming since the graphics of the game has developed enormously since its first
release.

The first video game made was a tennis simulator called Pong
which only made use of white square-shaped pixels on a black background
(switched off pixels). The pixels on screen were used to represent the two
paddles, one for each player, a line to divide the screen in the middle, to
give the idea of a tennis net, and the ball. The game was a great success and
it inspired a lot of games that have come after, like Space Invaders and
Pac-Man, where the games were also made out entirely of pixels graphics.

Another iconic pixel character is Mario, originally from the
Super Mario Bros. video game released in 1985 by Nintendo. The character of
Mario was created with a big nose and mustache in order to hide the lack of
facial detail and to avoid creating the animations for the mouth and take unnecessary
memory space and also because the NES system had a screen resolution of only 256x240
pixels.
The first graphics software program that enabled users to
create pixel art was known as SuperPaint, released by Richard Shoup in 1972. After
that, in 1977, the video game console Atari 2600 was released, and it contained
2D sprites in games such as Space Invaders and Pac-Man.
Even though pixel art began due to the restrictions of the
hardware used, it is still popular nowadays and has been used to create modern
games such as Citypixel and Habbo, and also games on hand-held devices such as
Nintendo DS, PS Vita and cellphones, such as snake. Some designers still use
pixel art today due to the sharp art one can produce and also due to the fact
that since the sprites do not take up too much memory space, the animations will
run smoother given the advancements in the hardware nowadays.

In order to create these assets I opened a new document, zoomed at around 1000%, and then used
the pencil tool with 1px in size. Then to save it in a large size, I copied the image created
in a new project, go to image size (Alt + Ctrl + I), change the width and
height to 1600 and select ‘Nearest Neighbor (preserve hard edges)’ from the
drop down menu at the bottom of the window.
The main difference between pixel art in real life and
digital pixel art is pretty evident; digital pixel art is displayed on screen
while real life pixel art can be done by any object that basically has a
circular or square shape, in order to create an image.
After the great impact that popular games such as Pac-Man
and Pong made, the idea of having pixel art in gaming has inspired pixel art
all over the world, and nowadays it is not used only in gaming, but also to
create pixel-like sculptures.
Even though pixel art is slowly fading away, it is still
being used by some game developers, even to create 3D games, such as Minecraft.
Many developers nowadays prefer to use vector shapes to create elements for
their games though, since they look more realistic and smooth. But even if in
gaming pixel art is not used so much often as it was once, recently there has
been a trend of artists that prefer to show pixels on display instead of normal
paintings.
One of the many mediums by which artists create real life
pixel art is the Rubik’s Cube. The Rubik’s Cube was invented in 1974, around
the time that pixel art was becoming popular. Josh Chalom is an artist who uses
the Rubik’s Cube as his canvas to create real life pixel-like art. This type of
art is interesting because from a far the art just looks like a pixelated
canvas, and only by seeing it up close can one realise that it is actually made
out of hundreds of Rubik’s cubes. Chalom explains how detailed this process of
creating pixelated art from Rubik’s cubes is, “ You have over 100,000 pixels
that you have to adjust and make sure that one’s correctly next to the other.”

John O’Hearn is another visual artist that creates pixel-like
mosaics using thousands of 6mm BBs. To produce his pixel art he makes use of a
computer program that he wrote which is connected to a machine that he invented
to help him turn any image into a mosaic. One of Hearn’s most notable work is
his Lebron James mosaic which uses 62,016 colored BBs.
