Artikulate is a pronunciation learning application currently in development in the KDE Edu playground. There are several blog posts in the web that explain its usage and also provide screenshots. In Artikulate we provide courses for several languages and within each course we have a set of lessons.

In this task you have to create two icons

1. one icon for "language course" and
2. one icon for "language course lesson"

Both icons should fit to each other and also fit to the overall set of icons as provided by the oxygen-icon package [1]. For designing those icons it could be a good idea to re-use icons/icon-elements from Oxygen. Your icons shall look fine in very small resolutions as well in big resolutions and it may be necessary to add different levels of details to them depending on their resolution (e.g., compare"x-office-address-book" with different details depending on the resolution).

You have to submit your result as a vector images in the svgz format and also provide png exports for sizes 16x16, 32x32, 48x48, 64x64. The icons must be dual-licensed under "LGPL version 3 or any later version as approved by the membership of KDE e.V." and "CC-BY-SA 3.0" unported.
