Using Python's 'turtle' module all it takes is a few lines of code to create engaging, colourful graphical patterns and designs.
If you don't have a Raspberry Pi you can still follow the series with these emulation instructions.
Here are a few extracts from Part 5:

Next time I'll continue the visual theme by introducing game programming with the PyGame module.
