Using Linux tools, create a mosaic portrait of yourself. Use a self-taken photo as a base and a set of tile images of your choice to complete the mosaic. Send the completed portrait for grading purposes to your teacher. The mark will not be based on artistic merit - the mosaic should be detailed enough so you are recognizable. For best results, use a high-resolution photo of your face only and have a tile library of at least 50 pictures, with varying colours and brightness. Do not forget to reference your sources if you use images not taken by yourself for tiles. Post your portrait on your blog if you like.
