Sketch is the nickname of a highly skilled Dance Dance Revolution player, who rose to become the best DDR player in the world circa 2004-2005. Anthony "Sketch" Carella is from New York and started playing DDR in early 2002, according to an MTV interview, because of a break up with a former girlfriend.
Various factors lead Sketch to completely dominate the East Coast DDR community around early 2004 by being able to SDG (Single Digit Great) songs in the video game, including the harder songs in the game ("10 footers") which was at that time impressive. His competitive edge was that he followed a JSB-style of play, where he was able to play songs in the game (in particular difficult songs called "10 footers") on various options, including a mode called shuffle that scrambles the arrows in the game around.
Most of his options scores (options are the modes such as shuffle that made the songs in the game more difficult) have only been surpassed by Johnny "JSB" Sheridan, another known DDR Legend who started playing DDR circa 2002 and became the best in the world at his time for his methodology and consistency. It is said that after a tournament in New York in 2003 which JSB attended, Sketch changed his style of gameplay in relation to JSB.
Sketch retired after a 2005 National Tournament held in the Jacob Javits Center in New York. MTV filmed the victory, where it can be seen on MTVs website or youtube.com. Sketch is also known for competiting in tournaments and beating top tier players without using the bar on the DDR machine, as well as not using speed modifiers to play his songs which allegedly makes the song easier to get a higher score on.
Sketch randomly posts on DDRfreak.com, where he claims to be retired in DDR and studying business and investing.
