Knotter is a highly configurable interlace designer. Interlace patterns are a kind of design historically used as a decorations in many places and by different cultures (some examples are Celtic knotworks and Islamic interlaces). Knotter aims to allow its user to design such patterns in an intuitive way and to provide easy ways to integrate the result into external general-purpose graphic software. For this purpose, designs created within Knotter can be saved in a custom human-readable format and exported as Scalable Vector Graphics and in a wide number of raster image formats.
Golem Python Framework is a Python game framework for developing and learning. It can assist a student of programming by providing opportunities to write programs with interestingly visible effects, despite their simplicity. Golem provides a Web-based interface that can be used even by very early students to learn the basics of thinking with computer code by teaching a visible character on the screen to perform various tasks. Golem is based on Python, and allows a student to use all of Python's features. It attempts to hide the intimidating face that computer programming can present. Learners who are too advanced for the Web interface can use Golem as a powerful Python development framework that is effective for developing cross-platform 2D games.
