Systems and methods for interacting with a visual programming system.. The subject matter includes a "radial" menu that eases selection of options. The radial menu has a hierarchical feature, lower levels being activated when radial menu choices are selected, and higher levels being activated when a central menu option is activated. The user can invoke a plurality of software articles, such as input and output devices, applications, programs, and the like, and can create a custom application by connecting one or more outputs from one software article to inputs of one or more other software articles. A group of interconnected software articles can be encapsulated, and represented as a user-created software article.
