Gobo is a sprite that comes with all installations of Scratch. Gobo was named by Scratch Team member Natalie Rusk. It was drawn by Wing Ngan. On February 14, 2011, the Scratch Team announced that Gobo was the ninth most common sprite used in projects uploaded to the Scratch Website (after buttonPressed). It is unknown how commonly the sprite has been used more recently.
A modified version of Gobo is used as the logo for the Scratch modification Build Your Own Blocks. It has a "tail" depicting the Greek lowercase letter lambda (λ), which, in computer science, represents the time window over which a process is observed for determining the working memory set for a digital computer's virtual memory management.
