My year 8’s recently did a project on creating pictures using transformations on geogebra. It turned out to be an absolutely brilliant task and some of the pictures they came up with were infinitely more creatively than I could ever do. I did realise half-way through however that the focus was starting to be more art based than mathematical and therefore asked them to provide a step-by-step process of instructions which anyone could use to recreate their picture. This definately helped to remedy the problem.
See some of the pictures below.
Transformation Birds – combination of refelctions, translations, enlargements and rotations. (See Transformation birds for instructions on how to make)
