Ångström distribution instance of Linux distribution
The Ångström distribution is a defunct Linux distribution for a variety of embedded devices. The distribution is the result of work by developers from the OpenZaurus, OpenEmbedded, and OpenSIMpad projects.  The graphical user interfaces (GUIs) available are OPIE and GPE among other options.
The Ångström distribution is in "competition" with Poky Linux.  Ångström is based on the  OpenEmbedded project, specifically the  OpenEmbedded-Core (OE-Core) layer.  While both Ångström and Poky Linux are based on OE-Core, mostly utilize the same toolchain and are both officially "Yocto compatible", only Poky Linux is officially part of the Yocto Project.
Ångström primarily differs from Poky Linux in being a binary distribution (like e.g. the Debian, Fedora, OpenSuse or Ubuntu Linux distributions), using opkg for package management.  Hence an essential part of Ångström builds is a binary package feed, allowing to simply install software distributed as opkg packages, without having to compile them first (just as one might install a binary package with  aptitude or dpkg).
