By Geek I don't only mean to play videogames music. I also mean to play music using weird stuff like Beer Bottles, iPads and hitting anything that can make a sound! Sometimes in Stop Motion, sometimes in VideoSongs, I usually play songs from old videogames like Tetris, Zelda, Mario, etc.
Pixel art is a form of digital art, created through the use of raster graphics software, where images are edited on the pixel level. Graphics in most old (or relatively limited) computer and video games, graphing calculator games, and many mobile phone games are mostly pixel art.
Here's some pixel art featuring a lot of Nintendo characters like Mario Bros, Mega Man and Link from Zelda, using shots, jelly beans, etc.
