Silent Scope is an arcade game that puts the player in the shoes of a sniper during a series of terrorist incidents. The game uses a rifle that is mounted on the console, requiring players to physically alter their position in order to shoot accurately. In addition, the rifle's scope displays a close-up view of a small portion of the screen, representing the sniper's long-range view of the area where the rifle is pointed. The game spawned three sequels: Silent Scope II, Silent Scope 3, Silent Scope EX which was released only on arcade systems and a version for the Game Boy Advance. A port has been released for the iPhone OS. The game was offered for a $.99 promotion from August 27 to August 29, 2009 on the App Store. A Reboot of the series was in development at Day 1 Studios, but Konami cancelled it at the end of 2011. The game was a Stealth Third Person Shooter and was in development for PlayStation 3 and Xbox 360. Konami is developing a new Arcade game of the series, titled "Silent Scope: Bone Eater". The game will be released in the Arcades in 2014 in Japan.

Sitting Ducks is a lithograph created by Michael Bedard in the late 1970s. It depicts a literal interpretation of the idiom "sitting duck". Three ducks are relaxing in the sun on white chairs by the poolside, one looks up and notices two bullet holes in the wall. Bedard then went on to create an entire series of "Sitting Ducks" related lithographs, which culminated in a children's book and a cartoon series.

SK8 (pronounced "skate") was a multimedia authoring environment developed in Apple's Advanced Technology Group from 1988 until 1997. The project's goal was to allow creative designers to visually create a complex, working application. This was to be done by elegantly separating the concerns of visual design from programming. The main components of SK8 included the object system, the programming language, the graphics and components libraries, and the Project Builder, an integrated development environment. It was described as "HyperCard on steroids". SK8 was a research project that resulted in a variety of spinoffs (e.g., AppleScript, IPC for the Mac) and was used by Apple for system-level QA and for prototyping QuickTime and Newton, and by universities and corporations for creating and prototyping various tools and applications. Although around 1993 a team was assigned by the Apple Product Division to release a SK8 runtime, the limitation of the Mac's capabilities (mainly, low RAM and processing power) as well as the shift to the PowerPC chip made such a large project intractable. With the bulk of the original vision completed and no easy path to release as part of MacOS, active development ended in 1996-1997, and the Macintosh Common Lisp source code for the entire project was released to the public in 1997.

Sky Dancers is the name of a line of toys and an animated show spin-off that were popular in the mid-1990s. The toys were constructed of a pull-string base and a doll with foam wings. When the doll was inserted into the base and the string pulled, the doll would launch into the air, spinning its wings like a propeller as it flew.
